What is ilmenite?

The name of the stone was proposed by the German geologist Gustav Rose, who conducted research in the Urals and Siberia. It was a unique expedition led by the famous scientist A. Humboldt, which took place in 1826. The find is named so because it was discovered for the first time in the Ilmensky mountains in the Chelyabinsk region.

Ilmenite belongs to the class of titanium minerals, formed in nature are found quite rarely and are in great demand among stone connoisseurs and collectors. Ilmenite also known by a different name titanium iron ore, that is, it is a valuable ore, from which very valuable titanium is mined.

Description and properties of ilmenite

Ilmenite belongs to the class of oxides and hydroxides. The chemical composition of ilmenite is titanium oxide with a sufficiently high content of iron, magnesium, and also, which has a special layered structure. However, the composition is unstable, conditionally chemical formula ilmenite can be described thus: FeTiO3 (36.8% Fe, 31.6% O, 31.6% Ti). Hematite and ilmenite have a very similar crystal structure, it is not uncommon to find natural compounds when a solid solution is present in ilmenite.

Usually in nature, ilmenite occurs in the form of flattened crystals, but there is another form, but much less often - rhombohedral crystals. Most often they are granular masses. For collectors, the so-called iron or titanium roses are very valuable, they are well-formed crystals with a complex shape.

Usually these roses look like they have a gorgeous metallic sheen. Photo of ilmenite really fascinate with their beauty, but of course this mineral is best viewed in close proximity, then you can appreciate its brilliance and color play.

Ilmenite coloring it can be black, like a titanium rose, or dark gray, sometimes even brownish; however, mostly black stones are found. The luster of stones is always the same - metallic. Ilmenite is a brittle natural material, and the fracture of such a stone is conchoidal. Mineral ilmenite it can shine through with a reddish color, sometimes brownish only in very thin chips, and in general this mineral is considered opaque.

Most ilmenites that occur in nature are weakly magnetic, this is due to the fact that they may contain magnetite as impurities. It should also be noted that the ilmenite mineral is not affected by an acidic environment, that is, it does not dissolve in acid. The hardness index of this stone is 6-7 units.

The use of ilmenite

Lithotherapists widely use the mineral ilmenite in the treatment and prevention of diseases. First of all, this information is of particular importance for people who have iron deficiency problems in the body, since regular wearing of this stone in the form of beads either significantly improves the situation. Also, it is believed that it is ilmenite that has a beneficial effect on the main fluid of our body - blood, this wonderful stone favors the cure of diseases.

They make and from ilmenite, they give a person strength, make him more courageous, hardy, brave and strong. There is an opinion that this stone contributes to the development of an “iron” character in humans, since the mineral itself contains a large proportion of iron. Ilmenite amulets are highly valued by people who cannot imagine their lives without extreme sports, where reliable protection and patronage of stones is needed.

Astrologers, in turn, warn people under the signs, and from wearing this stone. He acts too actively on them and awakens not the best qualities of a person. Ilmenite affects people of fiery signs badly and makes them too aggressive and quick-tempered, it becomes quite difficult for them to control their negative emotions, but for the rest this stone is well suited and you can safely use its properties.

Ilmenite is also highly valued in the industrial sector, with the use of this mineral many useful things are done. Without ilmenite, the production of titanium white would be impossible; it is also used in the production of a filler for plastics and various enamels. In metallurgy, titanium and titanium are mainly obtained from ilmenite, which are highly valued on the market.

Deposits and mining of ilmenite

This natural mineral is widely distributed, however, large druze and beautiful crystals are rare. The processes of weathering and erosion affect ilmenite, therefore, because of them, you can most often find ilmenite sand. Inclusions of this mineral have been repeatedly found in and field. In many countries, deposits are being developed that carry industrial significance. . In Russia, ilmenite, as in many other countries, is available in fairly large quantities.

In the Urals, in the area where that mineral was first found, specimens of this stone were found, which weighed up to 60 kilograms. Russia is known throughout the world for its Tugan Mining and Processing Plant "Ilmenit", this enterprise is engaged in the development of the deposit and the production of sands and concentrates.

The mineral ilmenite is found in Norway, Finland, Sweden, Canada and Italy, as well as in other countries. Ukraine, namely the Ukrainian shield, is rich in this natural substance, there is evidence that it contains approximately 900 million tons.

However, the world's largest deposit, or rather an ilmenite quarry, is considered Tollnes, which is located in Norway. Ilmenite mining rather time-consuming and costly process, it involves, as a rule, a large number of workers in this field of activity. No wonder ilmenite is considered a moonstone, as many studies suggest that the lunar soil is enriched with this mineral.

Ilmenite price

As statistics show, ilmenite price constantly growing, this is due to many reasons. For example, in 2011 the price of ilmenite fluctuated around $120 per ton, but in 2012 this price increased to $300. For the current 2015, this price was even higher.

A further increase in prices for this mineral is also predicted. As for individual stones, many collectors are willing to spend thousands of dollars to purchase a single stone that will serve as an adornment and a valuable contribution to their collection.

If you are offered a talisman or amulet made of ilmenite at a low price, then you should think carefully about purchasing such an accessory, as it may turn out to be a fake and a hoax. Therefore, do not count on a dozen rubles when buying a real ilmenite, it should cost at least an order of magnitude more expensive.

Thus, you will really get what you need, and then you will undoubtedly feel the influence of this stone on your body and character. An appointment with a lithotherapist and a procedure with ilmenite is also quite expensive, and a large number of such sessions will be required to treat blood diseases.

This group of solid minerals in the territory of the Omsk region is represented by reserves and resources of titanium and zirconium of the Tara and Borisovsk-Pavlograd placers, located respectively in the northern and southern parts of the region.

Titanium and zirconium

Titanium - zirconium raw materials of the Tara placer were discovered during prospecting - revision work in 1959-1960, a detailed study of the placer was carried out in 1989-1995. results of deep geological mapping (GGK-50), geological additional study of areas (GDP-200), in 1993, preliminary and detailed exploration of the Experimental block of the Left-bank placer area was carried out with the calculation of reserves in categories В+С 1 . Based on the results of exploration work (prospecting – “evaluation work on the Left Bank site of the Tara zircon – ilmenite placer”), ore areas were delineated and reserves were estimated. At the Borisovskov-Pavlograd site, according to the results of geological survey work (GGK-200) and geological additional study (GDP-200) of areas in 1989-2002. the ore-“placer area of Borisovskov” of the Pavlograd placer has been identified, and the probable zirconium resources have been estimated.

Halo dispersion of titanium–zirconium mineralization Borisovsko Pavlogradskaya placers occur at a depth of 107–110 m in sandy–silty deposits of the Upper Oligocene, established by single ore intersections. The total area of the alluvial area of the same name is 1.5 thousand square meters. km. Within its boundaries, 5 alluvial fields with a total area of 120 sq. km with cost-effective predictive resources in category P 2 for only one Borisov alluvial field with an area of 23.7 sq. km.

The predicted resources of zirconium (in terms of ZrO 2 ) for the Borisov alluvial field, approved by the Ministry of Natural Resources of the Russian Federation as of 01.01.2003, amount to 380 thousand tons in category Р 2 conditional ilmenite content 60 kg/m 3 , minimum industrial capacity 1 m).

Tara placer It is represented by fine-grained watered sands of the Novomikhailovskaya Formation of the Lower Oligocene. The Irtysh River conditionally divides the placer into two parts: the left bank, with a productive stratum depth of 53–55 m, and the right bank, with a productive stratum of 43–110 m. Ore minerals are ilmenite, leucoxene, rutile, anatase, brookite, zircon, monazite useful components are titanium dioxide and zirconium. The zircon-ilmenite sands of the Tara placer contain rare and rare earth elements: cerium, hafnium, lantal, ytterbium, samarium, terbium, gadolinium, etc.

According to the degree of exploration (as of 01.01.2010) within the Tara placer, the following are distinguished: the Kalinin ore field (TiO 2 and ZrO 2 resource assessment in category P 2); Tara alluvial field (assessment of TiO 2 and ZrO 2 resources in category Р 2); the southern part of the Levoberezhny block (estimation of reserves in category C 2); Experimental block of the Left Bank area (reserves of TiO 2 and ZrO 2 in categories B and C 1).

Predicted resources of titanium (TiO 2), zirconium (ZrO 2) of the Tara placer as of 01.01.2003 were tested in specialized institutes and approved by the Ministry of Natural Resources of the Russian Federation; reserves of titanium (TiO 2) and zirconium (ZrO 2) were approved by the State Reserves Committee of the Ministry of Natural Resources as of 01.01.2007 (minutes no. 1370 dated 06.04.2007).

The allocated fund includes the Pilot block of the Levoberezhny area, where OOO Tarsky Gornov - Concentration Plant conducts pilot industrial work on debugging the technology of borehole hydroproduction (SHD). The sands are transferred to the processing plant, where, after gravity separation, they are stored in the form of primary concentrate. In 2009, no ore sands were mined at the Experimental block.

The undistributed fund includes the Levoberezhny site (southern part) of the Tara zircon - ilmenite placer, the reserves of which are in the state reserve on the balance sheet of the Subsoil Use Administration for the Omsk Region.

In the Omsk region, the total explored reserves of the Tara zircon - ilmenite alluvial deposit as of 01.01.2010 are shown in Table 1.3.

Ilmenite formula

Chemical composition

The chemical theoretical composition for FeTiO 3 : FeO - 47.34; TiO 2 - 52.66. The composition is unstable. Usually contains Fe 2 O 3 , which is isostructural with FeTiO 3 . Often the content of Fe 3+ is associated with an admixture of hematite or magnetite (decomposition of a solid solution of Fe 2 O 3 in FeTiO 3 ). Sometimes the observed slight excess of TiO 2 is due to an admixture of rutile.
Fe 2+ is partially isomorphically replaced by Mg and Mn 2+ , the content of which varies significantly (increased in magnesian and manganese varieties - picroilmenite and manganilmenite). Mg is typical for ilmenite of kimberlite rocks.
In many ilmenites, especially those associated with alkaline rocks, there is a small admixture of Nb, which was not previously determined in the analysis (for example, Nb is not indicated in numerous old analyzes of ilmenite from the Ilmensky Mountains, and in all modern analyzes it is noted; the maximum content of Nb 2 O 5 - 3.80% is noted for one of the ilmenites of the Vishnevye mountains. In some cases, however, the presence of niobium is due to the presence of inclusions of columbite. For ilmenite from basic rocks, the presence of V, Cr, Co, and also Ni is typical. Other impurities were observed: Sc - up to 0.027%; Zn - up to 0.57% ZnO in manganese ilmenite from Kounrad granite; Sn - 0.015% in ilmenite of the Dalidat massif in the Lesser Caucasus; Ba - 0.04% BaO and Sr - 0.004% SrO - in Lovozero manganese ilmenite; Y - 0.75% Y 2 O 3 - in manganilmenite from the Far East; Th - in accessory ilmenite from urtite of the Lovozero massif; an insignificant admixture of Cu is indicated for ilmenite from Greenland gabbro.

Varieties

Picroilmenite- picroilmenite with partial isomorphic substitution of Fe 2+ for Mg, contains 20 or more percent MgTiO 3 (9 or more percent MgO), is an intermediate mineral between ilmenite proper (crichtonite) and geikilite. It is typical for ultrabasic rocks (kimberlites, etc.), chromite deposits.
Named from the Greek "picros" - bitter in connection with the content of magnesium (Groth, 1898).
Synonym: picrotitanite - picrotitanite (Dana, 1868), picrocrychtonite - picrocrichtonite (Lacroix, 1901).

Manganilmenite- manganilmenite (Simpson, 1929) contains 13% or more MnO, an intermediate mineral between ilmenite proper and pyrophanite.

Yttromanganoilmenite(yttromanganoilmenite) - manganilmenite containing 0.75% Y 2 O 3 (Lozhnikova and Yakovleva, 1961) - an extra name.

Silicoilmenite- silicoilmenite, based on a microscopic study of sections of ilmenite from the Ilmensky mountains, Pilipenko previously identified red-brown grains that form oriented intergrowths with typical ilmenite, as well as pegmatite intergrowths of ilmenite with silicate (microcline?); red-brown grains were presumably taken by him as a solid solution of a silicate substance in ilmenite, but remained unexplored.

Crystallographic characteristic

Syngony. Trigonal.

Symmetry class. Rhombohedral - 3.

Crystal structure

Corundum type structure. Fe 2+ and Ti 4+ are in six-fold coordination, taking in turn the places of the Al structure of corundum.

The form of finding ilmenite in nature

Shape of crystals. Crystals from thick tabular to lamellar along (0001), less often rhombohedral crystals formed by (1011) or sharper rhombohedra are observed.

Doubles according to (0001) and (1011), sometimes polysynthetic, often observed in thin sections. Twinning in some ilmenites is due to mechanical influences. In thin sections, oriented intergrowths with hematite, corundum, and chromite are established. Oriented intergrowths with magnetite are observed, (111) and (111) of which are parallel to (0001) and (2021) ilmenite. In intergrowths with rutile: (100) and rutile parallel to (0001) and or (1010) and ilmenite. Oriented intergrowths with perovskite, augite, hypersthene, and mica were also noted.

Aggregates. Dense, irregularly shaped discharges, grains are often tabular, crystals from small plates to large ones (several tens of centimeters).

Physical properties

Optical

The color is iron-black, sometimes with a brownish or steel-gray tint.
The streak is black, sometimes brownish-black.
The luster is metallic or semi-metallic.
Transparency Opaque. Only in the thinnest fragments is it faintly translucent with a reddish-brown color.

Mechanical

Hardness 5-6.
Density 4.6-4.8; the entry of Fe 3+ increases, and Mg and Mn 2+ reduce the density. With leucoxenization of a mineral, its density decreases.
Cleavage is not expressed; separation is observed along (0001) and along (1011) as a result of twinning.
Fracture from conchoidal to semi-conchoidal.

In crystals, it is similar to hematite, from which it differs in the color of the line. In solid precipitates, it resembles magnetite, but unlike it, it has much less pronounced magnetic properties; in addition, in contrast to magnetite, when boiled in HCl for 1-3 minutes, it retains its luster. In concentrates, it is sometimes difficult to distinguish from chrompicotite (a reaction to chromium is required), columbite-tantalite (with prolonged calcination at 900 °, ilmenite becomes dull), from other black minerals of concentrates - amphiboles, pyroxenes and tourmaline (after heating to 800 °, it is easily attracted by a magnet or electromagnet).
In polished sections, it differs from magnetite in anisotropy (except for cuts along the basis), in resistance to etching (it must, however, be taken into account that titanium-rich magnetites are often difficult to etch).

Associated minerals. Hematite, magnetite, apatite.

Origin and location

An important accessory mineral of diabases, gabbro and other rocks of basic composition. Sometimes ilmenite forms microcrystalline ingrowths in pyroxenes. Ilmenite segregations are also found in alpine-type veins in association with rutile, sphene, apatite, feldspars, and rock crystal.

Widely spread. It is usually a primary, early mineral, rarely secondary, developing after titanite during metasomatism. A common accessory mineral of many igneous rocks, mostly basic, less often acidic: gabbro, anorthosites, diorites, etc. Sometimes it forms disseminated ores in basic rocks, closely associated with titanomagnetite in titanomagnetite ores. It is also known in metamorphic rocks, mainly in their main varieties - amphibolites, amphibole or pyroxene gneisses.
Characteristic of alkali syenites, nepheline syenites and their pegmatites, where it is usually observed in association with zircon. Picroilmenite is a typical kimberlite mineral.
Ilmenite occurs in quartz veins and in alpine-type veins. In the form of tiny plates, it is known as a decomposition product in titanium-containing minerals, for example, in titanomagnetite; sometimes enclosed in diallag, hypersthene, biotite, etc. Small clastic grains of ilmenite (usually leucoxenized) are found in sedimentary rocks - sandstones, marls, clays and bauxites. Being quite stable, stone material accumulates in placers.

Mineral change

It is steady, at destruction of rocks gets to placers. Often replaced by rutile and hematite, as well as magnetite; pseudomorphs of rutile and hematite after ilmenite are described. Known cases of substitution ilmenite titanite, perovskite, aeschinite, pyrochlore, davidite, etc. The leukoxenization of ilmenite is quite common - its replacement with a fine-grained aggregate, consisting mainly of rutile or anatase (less often brookite) with an admixture of iron oxides, etc .; ilmenite leucoxenization is especially characteristic of sedimentary rocks and placers.
In 1909, Palmer described arizonite, which was considered as a mineral with the formula Fe 2 Ti 3 O 9 . Later] it was proved that this is a mixture of oxides of iron and titanium, developing over ilmenite in the process of its change. Nevertheless, a number of authors use this extra designation for leucoxenized ilmenite - for "intermediate products" of the transition of ilmenite to leucoxene, and Bykov even calls "proarizonite" (proarizonite) an intermediate product between ilmenite and "arizonite". The product of alteration of ilmenite, intermediate between ilmenite and rutile, is also described under the name pseudorutile (pseudorutile).
Pesche, Ernst, Tsvetkov and Shchepochkina (new data on the study of the Fe 2 O 3 - TiO 2 system) failed to synthesize Fe 2 Ti 3 O 8 - “arizonite”, and only Karkhanavala notes the formation of an unstable Fe 2 O 3 - TiO 2 system phase Fe 2 O 3 - 3TiO 2 , whose composition corresponded to "arizonite".

Ilmenite deposits

Locations ilmenite very numerous. In Russia, it is common in titanomagnetite deposits associated with gabbro in the Urals, Altai, Kola Peninsula, etc. It is also found in chromite deposits in the Urals and in other areas.
Ilmenite is found in pegmatites of nepheline syenites of the Khibiny tundra, the Ilmensky and Cherry mountains, the Mariupol alkaline massif, and in other pegmatites of the Lovozero Tundra (manganilmenite). In granitic pegmatites of Russia, ilmenite is rarer; well-formed crystals are characteristic. It is noted in some quartz veins, for example, in the Karaoba molybdenum-tungsten deposit in Kazakhstan, on the Kola Peninsula, in the Yenisei Ridge and in other areas.
Picroilmenite is widely distributed in kimberlites and picrite porphyries of Yakutia (its content in different pipes is not the same, from 0.01 to 0.07 wt.%); there is a direct relationship between the content of ilmenite and large mica segregations in kimberlites and an inverse relationship between its content and the content of chrome spinels and chromium diopside.
Ilmenite is noted in the composition of sedimentary rocks of various regions of Russia, sometimes it is found in placers in an increased amount: placers of Ukraine, the Turgan deposit, etc.
Of the foreign deposits, the most significant are ilmenite-bearing veins in gabbro pcs. Washington and New York, in peridotites sht. Kentucky and disseminated ores of anorthosites pcs. Wyoming in the USA, in Canada - lenses and veins in anorthosites of Quebec, in Norway veins in diorite (large Telies deposit), in India - syenite veins; in France, Switzerland and Italy, ilmenite is observed in alpine-type veins.
Widespread in placers in California, Brazil, Anglin and other countries. The largest placers rich in ilmenite (with zircon, etc.) are known in Florida (USA), along the coast of Travancourt (India), and in Balangod in Ceylon (picroilmenite and geikilite).
Ilmenite is also observed in some stony meteorites with nickel-iron, troilite, and chromite.

Practical use

Titanium ore. It is used to obtain an alloyed alloy with iron (ferrotitanium), as well as in the form of titanium dioxide - a white paint with high hiding power.

Physical research methods

Differential thermal analysis

ancient methods. Under the soldering tube, only in very thin fragments, it is slightly melted along the edges. After calcination in a reducing flame, it becomes magnetic.

Crystal optical properties in thin preparations (sections)

In thin sections in transmitted light, it is slightly translucent (dark brown). Single axis (-). n > 2.5. The birefringence is very strong. In polished sections in reflected light - grayish-white with a slightly brownish tint. Double reflection in air is weak, distinct in immersion, especially in the presence of twins: Ro - white, pinkish-brown, Re - darker, brown. Clearly anisotropic. Internal reflections are rarely observed (dark brown). Quite common are twinning and characteristic structures of the decomposition of solid solutions (inclusions of hematite, magnetite, rutile, chromite, etc.). Sometimes there is a zonal structure.

Send your good work in the knowledge base is simple. Use the form below

Students, graduate students, young scientists who use the knowledge base in their studies and work will be very grateful to you.

When selecting gross sample sand from the material being tested is removed from the pit and stored in a specially cleared area. The entire discharge is carefully shoveled and every 10th shovel enters the sample, then the material is collected in a cone, which unfolds into a disk 0.10 - 0.15 m high. Further, a sample weighing 35 - 50 kg, which is supplied for washing on laboratory concentration tables.

Technological samples are selected according to standard sands from pits and wells.

From pits all the material from the reservoir enters the sample, which is shoveled and brought to the weight required for technological tests using the ring and cone method. In the case of taking a technological sample from several workings, the amount of material entering the sample is taken in proportion to the thickness of the pay zone.

When compiling a technological sample from wells, waste material enters the sample. After processing ordinary core samples, the amount of material entering the sample is also taken in proportion to the thickness of conditioned sands.

In order to study the quality of quartz sands and kaolin obtained after the extraction of the ore component, group samples are being prepared. Group samples are compiled from individual material of ordinary core samples for the entire thickness of conditioned sands. The amount of material in the group sample is supplied in proportion to the intervals of ordinary samples.

3.7. Sample processing

The sample received for processing is dried, weighed, and with the help of hand rolls, lumpiness is destroyed in it. Then, using the ring and cone method, the sample is brought to a final weight of 150-200 g. Simultaneously with the sample, two duplicates are made. Duplicate No. 1 weighing 1250-200 g and duplicate No. 2 weighing 1000-400 g. In addition, all waste material of samples is collected for the preparation of technological, experimental, group and other samples.

3.8. Analytical works

All routine samples taken at the deposit must be subjected to mineralogical analysis for zircon, ilmenite, leucoxene, rutile and monazite. The bulk of the analyzes will be carried out in the mineralogical laboratory of the Tomsk Complex Expedition. Significantly fewer samples will be analyzed in the base laboratory at Tomsk Polytechnic University. Some individual wells completed at the beginning of the exploration of the field will be analyzed in the laboratory of the Ural Geological Administration.

The table below shows the placement of samples involved in the calculation of reserves for various categories.

To assess the degree of opening of titanium-containing minerals, zircon samples are analyzed for the content of titanium and iron. Analyzes must be performed according to the standard method, including the fusion of zircon with potassium pyrosulfate, leaching of the melt and preparation of a solution for the direct determination of titanium. The determination was carried out by the photometric method according to the color intensity of the diantipyrylmethane complex, depending on the titanium concentration. Iron is determined according to a standard procedure based on the titration of Fe+3 with Trilon B at pH 2 to 3 with sulfosalicylic acid as indicator. In this case, titanium in solution is fixed in the form of a tartrate complex. All rare and rare earth elements that are part of the original concentrate and products of its processing will be determined by neutron activation analysis.
The analysis is based on measurements of the radioactive emission from nuclei excited in the neutron flux of the IRT-T reactor.
Neutron activation method compared to traditional spectral emission analysis, it allows to determine the content of rare earth and other elements capable of absorbing thermal neutrons of elements in the analyzed substances with a higher accuracy.
The analyzes will use the relative method. In its implementation, simultaneously with the analyzed sample, a standard sample with known concentrations of various elements is irradiated, after which the standard and analyzed samples are measured under the same conditions.
The material composition of productive deposits must be studied with completeness, which makes it possible to assess the industrial value of the main and all associated useful components, as well as to take into account harmful impurities. Their content in the reservoir is established on the basis of analyzes of samples obtained during processing (washing) by mineralogical, chemical, spectral methods.
If there is experience in processing similar sands in industrial conditions, it is possible to use the analogy method, but the results of its application must be confirmed by the results of laboratory studies.
As a result of laboratory studies, the technological properties of all selected industrial (technological) types of sands will be studied to the extent necessary for the selection of technological schemes for their processing, providing a comprehensive and most complete extraction of the main and associated components, as well as the possibility of cleaning industrial waste.

3.9. Sampling control.

3.9.1. Sampling control

For control, the material is additionally washed out from the discharges of the pits, for titanium-zircon placers from the core of the wells remaining after the selection of the main samples. In the case when all the material was sent to the main samples, the reliability of the sampling is established according to the data of the control work. The purpose of conducting control work is to establish the reliability of the results of exploration performed by wells (whether the thickness and position of the productive formation in the vertical section of the placer are correctly determined), as well as the presence or absence of a systematic error in testing the placer by wells.

Control is subject to 5-10% of wells, the data on which are used in the calculation of reserves (balance sheet and off-balance sheet).

It is necessary to go through at least 20 control workings located in several exploration lines that completely cross the industrial contour of the placer and characterize both enriched and poor areas, control pits are located directly on the well.

To control the furrow sampling method, bulk samples are taken. The sampling interval for the bulk sample is similar to the interval for the furrow sample.

3.9.2. Sample Processing Quality Control

At enrichment plants, samples are processed in order to obtain a concentrate. The thoroughness of the washing of samples and the completeness of the extraction of components is controlled by recleaning the tailings at installations that provide the most complete capture of useful minerals, as well as by quantitative analysis of tailings samples.

Control washings characterize the quality of sample processing in certain periods (months, quarters), as well as the completeness of the extraction of useful components from loose deposits of different grain composition.

3.9.3. Analytical work control

The analyzes performed by mineralogical, chemical, spectral and nuclear geophysical methods must be systematically verified by performing internal and external control analyzes of ordinary and group samples.

The work of the main laboratory is controlled during the entire period of exploration of the deposit. The work of analyzes performed both for the main and associated components is subject to control.

To clarify a random error in the analyzes performed by the laboratory of the Tomsk Complex Expedition, systematic internal control will be carried out for zircon and ilmenite, leucoxene and rutile. Duplicate No. 1 is sent for internal control. The total number of controlled samples will be 836 - 10.2% of the samples involved in the calculation of reserves.

To determine the accuracy of the determination by the laboratory of the Tomsk complex expedition, which performs a routine analysis, an external control is carried out. Duplicate No. 2 was sent for external control. External control is carried out in the chemical-analytical laboratory of the geological exploration trust No. 1 MG and ON for zircon, ilmenite, leucoxene and rutile. 486 samples will be subjected to external control, which is 6.1% of the number of samples included in the reserve calculation.

In addition, during the work, samples processed on concentration tables will also be subjected to external control. Which will be carried out in the chemical-technological laboratory of the geological exploration trust No. 1 in the amount of 28 samples, which is 6.2% of the samples washed on the tables that are involved in the calculation of reserves.

4. CALCULATION OF RESERVES.

The general calculation of the reserves of titanium and zirconium for the Tugan ilmenite-zircon placer deposit was made as of July 1, 1961. At the same time, the reserves of hafnium in zircon, monazite, quartz sand and kaolin were calculated in the balance and off-balance reserves of ore-bearing sands.

The conditions for the Tuganskoye deposit were drawn up, according to the assignment of the Tomsk Economic Council dated November 1, 1957, by the state special design institute and approved as temporary protocol No. 46 dated September 2, 1958 by the USSR State Planning Commission.

In connection with the preparation of this report with a general calculation of reserves, the Tomsk Economic Council and the Tomsk Expedition in March - May 1961 applied to Giredmet and the State Planning Committee of the USSR with a request to approve the temporary conditions for the Tuganskoye field previously developed by Giredmet (GSPI-1) as final. As a result, the temporary conditions for the deposit were left unchanged and confirmed by letter No. 30-158 dated June 17, 1961, the chairman of the commission of the State Planning Committee of the USSR for the approval of conditions for ore-mineral raw materials, comrade P.M. Postnov.

When calculating reserves, the conditions approved by Protocol No. 46 of September 2, 1958 were taken as a basis, according to which it is proposed:

The cut-off content of conditional zircon, taking into account the content of ilmenite, according to the coefficient of reduction of ilmenite to zircon equal to 0.42, is taken to delineate the placer and calculate the balance reserves of 5 kg per cubic meter of sand.

The minimum industrial content of conditional zircon, taking into account the content of ilmenite according to its reduction coefficient specified in paragraph 1, for a geologically isolated area, as well as for the area delineated by the cut-off content of conditional zircon, is 2 kg per cubic meter of sand.

In the contours of balance sands, identify and calculate the reserves of zirconium and titanium with a conditional zircon content in sands of 30 or more kg per cubic meter of sands.

The minimum thickness of ore-bearing sands included in the calculation of reserves is taken to be 1 m.

Ore sands with a conditional zircon content of 15 to 22 kg per cubic meter of sand, taking into account the content of ilmenite by the reduction coefficient, are calculated separately, and their reserves are attributed to the off-balance group.

Calculate the reserves of quartz sand and kaolin in the contours for calculating balance and off-balance ore-bearing sands.

These conditions are compiled under the condition that the deposit has balance ore-bearing sands of at least 40 million cubic meters and the ratio of overburden to sands is not more than 1.5: 1, as well as the industrial use of associated components - quartz sand and kaolin. With an increase in overburden in excess of 1.5 cubic meters per 1 cubic meter of standard sands in a geologically isolated area, as well as in an area delineated by the edge content of conditional zircon, the content of conditional zircon in sands increases by 0.6 kg per 1 cubic meter sands for each unit of the ratio of overburden thickness to the power of conditioned sands.

When determining the conditions for complex titanium-zircon raw materials, the Tuganskoye deposit is evaluated primarily as a zircon one.

Taking into account the prospects for the development of the zirconium industry of the USSR for 1959-1965. it was established that the selling price for zirconium concentrate should not exceed 100-150 rubles per ton in new prices.

The ratio of prices for ilmenite and zircon concentrates is taken as 1:2. Since new prices for zirconium concentrates have not yet been approved, GSPI-1, when calculating the conditions, combined prices were adopted, namely: the current price for ilmenite 42% concentrates, which is 49 rubles 20 kopecks. per ton and the conditional price for zirconium concentrates (based on a price ratio of 1:2), which in the future will be 170 rubles. per ton.

Since it is planned to obtain ilmenite concentrates with a titanium dioxide content of about 52% from the sands of the Tuganskoye deposit, the ratio of prices for ilmenite and zirconium concentrates, respectively, will be 1:2.4.

A) The total industrial reserves of the sands of the deposit must be at least 45 million cubic meters. m.

B) The produced capacity of the mining and processing enterprise based on the Tuganskoye deposit must be at least 2 million cubic meters. m. per year.

C) Stripping ratio should not exceed 1.5:1 cu. m \ cub. m.

D) The minimum thickness of the industrial seam is 1 meter, with an average for the deposit of about 5 meters and an average overburden ratio of not more than 1.5: 1 kbm \ kbm.

The economic calculations were based on the indicators of the design task of the Verkhnedneprovsk mining and processing plant according to the following correction factors:

Direct costs for stripping and mining operations are taken with a coefficient of 0.65 to the indicators of the design task. The cost of drilling and blasting was taken according to the "price list for drilling and blasting" - 0.32 rubles per cubic meter. m. explosive mass, which corresponds to 0.06 rubles. for 1 cu. m. of extracted sands.

The average annual salary of workers is accepted taking into account the Siberian allowance (20%).

The cost of transporting sands from the quarry to the factory is 0.04 rubles. per ton per km according to data from other open pits and with a decrease (by 20-25%) due to an increase in freight turnover.

General expenses are taken for 1 cubic meter. produced sands in the amount of 0.7 of the design due to a significant increase in production.

The cost of electricity is taken according to the price list of Tomskenergo.

As a result of the correction factors applied above, the total cost of production and enrichment of one cubic meter of sands from the Tuganskoye deposit can be assumed conditionally in the amount of 4.2 rubles. and consists of the following costs:

Extraction of sands 0-35 rubles.

Repayment of overburden works 0-10 rub.

Transportation of sands 0-40 rub.

Enrichment 3-00 rub.

General and out-

production costs 0-34 rubles.

Due to the use of enrichment waste, the cost of production and enrichment can be reduced to 8.8 rubles. per 1 cubic meter Prices for quartz, molding sands and kaolin are taken according to the price list and amount to 0.88 rubles for quartz sands. per ton, for molding sands - 0.98 rubles. per ton, for kaolin (raw) - 1.25 rubles. per ton.

According to the Tomsk Economic Council dated February 28, 1958.

Methodology for calculating reserves

The geological structure of the placer and the adopted exploration methodology made it possible to apply a linear method for calculating reserves with a block based on one exploration line.

Comparison of the linear method of calculating reserves and the method of geological blocks, carried out by us for the blocks of category B of the Northern and Kuskovsko-Shiryaevsky areas, showed that the calculation data for different methods are close to each other. This made it possible to calculate reserves using the linear method, which was previously recommended by the chief geologist of GSPI-1, V.V. Mokrenok.

As an exception, C2 blocks of reserves obtained by extrapolation beyond the contour of C1 blocks are calculated using the geological block method.

The nature of the structure of the placer and the presence of two ore layers in the placer determined the calculation of reserves separately for each ore layer. In the case when the layers are not clearly separated from each other, or are placed by poor ores of small thickness (2-3 m), the lower layer was not independently calculated, but included in the calculation of the upper layer.

The reserves are calculated for the rock mass with the allocation of reserves in peat and seam.

In the blocks of balance reserves in the reservoir, the reserves of rich ores with a grade of 30 kg were calculated. per cube. m and more than conditional zircon in the sands.

The delineation of reserves was carried out in accordance with the established conditions. The reserves are classified into categories B, C1 and C2 and are divided into on-balance and off-balance.

The qualification of reserves by category was carried out in accordance with the density of the exploration network, hydrogeological knowledge and technological tests of the productive sands of the deposit. When assigning reserves to category B, an exploration grid of 200 by 100 m, C1-400 by 200 m,

C2-800 at 400 m. In addition, C2 category reserves were obtained by extrapolation beyond the C1 category reserves contour to a distance equal to half the exploration network distance adopted for this category.

The assignment of reserves in blocks to balance and off-balance was carried out in accordance with the conditions for the average content of conditional zircon, taking into account the thickness of peat. With an increase in the ratio of the thickness of peat to the reservoir more than 1.5: 1, for each unit of the ratio, an amendment was introduced for the minimum industrial content of conditional zircon in the amount

0.6 kg/m. cubed.

The thicknesses (seam, peat and rock mass) of the workings were determined by summing up the thicknesses of the individual tested intervals.

The average content of useful components for the development was determined as a weighted average for the thickness of the tested intervals according to the formula:

Avg=М1С1+М2С2+……….М С

М1+М2+……+М

Where: M- thickness of the tested interval, m.

With- the content of the useful component in the sample

In the event that a separate sample in the contour was not analyzed, then this interval was assigned the average grade for the industrial seam of this working, calculated without this sample.

The average power along the line (block) was calculated by the formula:

Msr=M1 L 1+ M 2 L 2+…….M nLn

L1+ L2+…….+ ln

Where: M- thickness of peat, seam or rock mass

L- length of working influence

Avg=C1 M 1 L 1+ C 2 M 2 L 2+……… CnMnLn

M1 L1+ M2 L2+……….+ MnLn

Where: WITH- average mineral content by production.

M- the average thickness of the formation (peat, rock mass) in terms of output.

L- the length of the influence of the working along the profile, equal to half the sum of the distances

between adjacent workings.

The obtained average data were extended to the area of the block based on one exploration line.

When calculating reserves of category C2 by the method of geological blocks, the average thickness for a block was determined as the arithmetic average of the capacities of individual workings included in the contour of the block; useful components was determined as a weighted average of the thickness of the contents of individual workings.

If there are no workings in the block obtained by extrapolation, for the average content of ore minerals and thickness, the content and thickness of the extreme working, located in the contour of the C1 category block, bordering on the extrapolated C2 category block, was taken. The average content and thickness were distributed over the entire area of the block.

The contour of the industrial layer along the line is interpolated for half the distance between the last ore (with industrial content of conditional zircon) and the next barren working, taking into account the geological boundaries of the ore suite. If the placer was not contoured, extrapolation of the block contours was applied to half the distance between the last workings, which showed the standard content of ore minerals in the reservoir.

Block areas were measured with a planimeter on a scale plan of 1:5000 and 1:10000 by triple measurement, from which average data were taken.

The deviations between the control and ordinary measurements of the area were 1-2 divisions of the planimeter.

The sand reserves in the blocks were determined by multiplying the area of the block by the average thickness of the block: V= S* M

Where S- block area in sq. m.

M- average power per block, m

The mineral reserves in the blocks were calculated by multiplying the sand reserves in the block by the average content of useful components in the block according to the formula:

Q = V* C

Where V- sand reserves in thousand cubic meters.

WITH- average content of useful components per block in kg/m. cubed.

The reserves of sands and ore minerals for individual categories and areas are obtained by summing up the reserves for individual blocks of the corresponding categories and areas, taking into account their balance sheet.

In general, reserves for the deposit were determined by summing up all reserves (with allocation into categories B, C1,: B + C1 and C2) for individual areas.

For recalculation of zircon reserves for zirconium dioxide, in ordinary and control samples, they are small. This issue is covered in detail in the chapter Exploration work.

CONCLUSION.

As a result of geological prospecting and exploration work in the area of the Tugan complex ilmenite of the zircon deposit, three large areas have been explored: Severny, Kuslovsko-Shiryaevsky and Chernorechensky.

A comprehensive study of the deposit made it possible, along with ore components, to investigate the non-metallic component of the placer and prove its great industrial significance.

As a result of the exploration of the Tuganskoye field, the following reserves were calculated.

Category. reserves	Volume sands, thousand m3.	zircon	ilmenite	Rutile leucoxene	monazite	Dioxide zirconium	titanium
Promplast V	10813	133,8	329,1	44,6	10,55	85,9	139,9
Promplast C1	219939	2537,2	6107,3	977,3	88,24	1610,6	2678,0
Total B+C	230752	2671,0	6436,4	1021,9	98,79	1696,5	2817,9
Promplast C2 Total B+C1+C2	35292	416,2	1049,9	173,5 1195,4	21,51	264,3	463,0

At the same time, off-balance reserves were calculated in the following quantities: sand 51102 thousand m 3, zircon 350.0 thousand tons, ilmenite 109.6 thousand tons, rutile + leucoxene 154.7 thousand tons and monazite 15.98 thousand tons.

Associated component reserves in balance block contours: quartz sand 366225 thousand tons, kaolin 89946 thousand tons, hafnium dioxide 39.41 thousand tons. The amount of rare in monocyte is 76.75 thousand tons, thorium in monocyte is 5.99 thousand tons.

As a result of technological studies, it has been established that for the enrichment of the sands of the Tuganskoye deposit, it is possible to use both flotation and gravity minerals in combination with the processes of electromagnet separation and electrostatic enrichment.

During enrichment, zirconium, ilmenite, kaolin and quartz sands were obtained.

The full integrated use of all processed raw materials, huge reserves, low cost of the products obtained, and the favorable economic position of the deposit allow us to raise the question of its fastest industrial development.

In 1988-1991, in connection with the changing requirements of the industry for this type of raw material, additional exploration of this object was carried out.

In 1992, new reserves of solid sands at the deposit were approved by Protocol No. 72 of the GKZ. As of 01.10.93, they amounted, thousand m3:

At the same time, reserves of the main and associated ore components were identified: zircon, ilmenite, rutile + leucoxene, monazite, oxides of zirconium, scandium, hafnium in zircon, titanium and scandium oxides in ilmenite and rutile + leucoxene, as well as reserves of non-metallic components: quartz and kaolinite .

It should be noted that the assessment of the scandium reserves at the deposit was made for the first time, after the work on the assessment of the ores of this object, carried out at the Tomsk Polytechnic University (Rikhvanov et al., 1991). According to the authors of this work, the calculation of reserves could also be carried out for vanadium, tantalum, niobium, and rare earths.

In the same period (04/07/1988), at the initiative of the Regional Committee of the CPSU, a representative meeting was again held in Tomsk on the problem of developing the Tuganskoye deposit. The First Secretary of the CPSU OK A.A. Pomorov, opening and closing the meeting, spoke unequivocally that the region would make every effort to “blow up” the problem of Tugan.

Thus, only near the city of Tomsk, in a zone with a well-developed infrastructure, unique reserves of zircon-ilment sands with colossal resources are currently localized, which makes this area one of the largest ore objects of this type in the world.

The symposium "Strategy for the use and development of the mineral resource base of rare metals in Russia in the 21st century" held in October 1998 in Moscow further strengthened our conviction that the most rational approach to the development of such deposits is their integrated development with the extraction of significant ranges of rare elements associated with zircon-ilmenite ores.

The demand for rare elements in the 21st century, which has been clearly identified in the world, which was discussed at the symposium of N.P. Laverov, E.A. Velikhov and leading experts in the field of high technologies using rare elements, allows us to speak with confidence about the great future of Tuganskoye ores and other deposits of Western Siberia, located in favorable geographic and economic conditions.

At the same time, the crisis situation and recent events in the world dictate a special approach to solving these problems in the Russian Federation.

In our opinion, in order not to finally become a raw materials appendage of the developed countries, at this stage of Russia's development it is not advisable to speed up the process of integrating the Russian economy into the world market. Such attempts will inevitably lead to the suppression or even the collapse of their own manufacturing industry. It is obvious that further reduction in the property of strategically important enterprises of the mining and metallurgical profile, which is owned by the state and ensures the national security of the state, can lead to the same results. The task of developing the domestic market or the market within the CIS should be considered a priority.

World development experience shows that industrial and scientific and technological development goes through transnational companies (TNCs) and financial-industrial groups (FIGs). Russian business can create its own TNCs in the CIS or international FIGs. To do this, it is necessary to unite the efforts of the regions in the formation in key industries, which include mining and metallurgical enterprises, "national leaders" with a controlling or blocking stake. Through indicative planning and other economic levers of the state, stimulate investment activity and increase the competitiveness of these leaders on a global scale.

Based on the above, the following conclusions can be drawn

1. Deposits of this kind are not only and not so much deposits of titanium, zirconium, quartz, kaolinite, but complex deposits of rare and rare earth elements with titanium, zirconium, quartz and kaolin.

2. The development of such facilities requires the use of non-standard approaches and processing technologies that make it possible to abandon the raw option for using ore (according to the principle “mining at your place, processing at our place, but everyone has their own profit and environmental problems”). Therefore, it is necessary to carry out deep complex processing at the place of production, with the production of semi-finished products and finished high-tech products with unique properties, using the powerful research and production potential of universities, academic institutions and enterprises of the military-industrial complex of the cities of Tomsk, Omsk, Novosibirsk and other centers that are part of the Siberian agreements."

Geomorphologically, the site is a relatively flat area, characterized by the alternation of crests of the northeast direction with wide depressions, sometimes swampy or occupied by oxbow lakes. The river flows in the northwestern corner of the site. Stepanovka 1-2 m wide with a wide flood and the formation of oxbow lakes in the spring (Fig. 3).

The absolute marks of the plot surface are 56-63 m.

The object of exploration and exploitation is a buried ilmenite-leucoxene-rutile-zircon placer composed of coarse-grained silt, less often fine-grained sands and fine-coarse-grained silt. The placer is confined to the upper part of the sediments of the Novomikhailovskaya suite and occurs at a depth of 50-70 m from the earth's surface (Fig. 4). The thickness of the productive formation varies from 13 to 24 m, on average 17 m, the thickness of its conditioned part (with a cut-off content of conditional ilmenite 60 kg/m3) - from 0.8 to 9.4 m, on average 4.2 m. unsustainable quality of the mineral (TiO2 content 8.0-100.6 kg/m3, ZrO2 0.59-24.9 kg/m3) and uneven distribution of the main useful components (ilmenite 12.1-167 kg/m3, leucoxene 1, 2-15 kg/m3, sums of rutile, anatase, brookite 0.17-8.3 kg/m3, zircon 0.9-37.8 kg/m3).

Prospecting and appraisal work was carried out at the site with the calculation of reserves in category C2. The reserves were calculated on the basis of technical and economic considerations with the following parameters:

The cut-off content of conditional ilmenite in the sample and the minimum industrial content in the block is 60 kg/m3;

The minimum thickness of the ore seam is -1 m;

Coefficients for converting the content of industrial minerals into conventional ilmenite for zircon - 3.93, rutile, anatase, brookite, leucoxene - 3.19, ilmenite 1.0 m.

The reserves of the site were taken into account by the NTS of the Natural Resources Committee for the Omsk Region (Minutes No. 2 of 06/30/99) and are shown in Table 2.

Technological samples are selected according to standard sands from pits and wells.

When compiling a technological sample from wells, waste material enters the sample. After processing ordinary core samples, the amount of material entering the sample is also taken in proportion to the thickness of conditioned sands.

3.8. Analytical works

3.9. Sampling control.

3.9.1. Sampling control

Control is subject to 5-10% of wells, the data on which are used in the calculation of reserves (balance sheet and off-balance sheet).

It is necessary to go through at least 20 control workings located in several exploration lines that completely cross the industrial contour of the placer and characterize both enriched and poor areas, control pits are located directly on the well.

To control the furrow sampling method, bulk samples are taken. The sampling interval for the bulk sample is similar to the interval for the furrow sample.

3.9.2. Sample Processing Quality Control

Control washings characterize the quality of sample processing in certain periods (months, quarters), as well as the completeness of the extraction of useful components from loose deposits of different grain composition.

3.9.3. Analytical work control

The analyzes performed by mineralogical, chemical, spectral and nuclear geophysical methods must be systematically verified by performing internal and external control analyzes of ordinary and group samples.

The work of the main laboratory is controlled during the entire period of exploration of the deposit. The work of analyzes performed both for the main and associated components is subject to control.

4. CALCULATION OF RESERVES.

The conditions for the Tuganskoye deposit were drawn up, according to the assignment of the Tomsk Economic Council dated November 1, 1957, by the state special design institute and approved as temporary protocol No. 46 dated September 2, 1958 by the USSR State Planning Commission.

When calculating reserves, the conditions approved by Protocol No. 46 of September 2, 1958 were taken as a basis, according to which it is proposed:

The cut-off content of conditional zircon, taking into account the content of ilmenite, according to the coefficient of reduction of ilmenite to zircon equal to 0.42, is taken to delineate the placer and calculate the balance reserves of 5 kg per cubic meter of sand.

In the contours of balance sands, identify and calculate the reserves of zirconium and titanium with a conditional zircon content in sands of 30 or more kg per cubic meter of sands.

The minimum thickness of ore-bearing sands included in the calculation of reserves is taken to be 1 m.

Ore sands with a conditional zircon content of 15 to 22 kg per cubic meter of sand, taking into account the content of ilmenite by the reduction coefficient, are calculated separately, and their reserves are attributed to the off-balance group.

Calculate the reserves of quartz sand and kaolin in the contours for calculating balance and off-balance ore-bearing sands.

Methodology for calculating reserves

The geological structure of the placer and the adopted exploration methodology made it possible to apply a linear method for calculating reserves with a block based on one exploration line.

As an exception, C2 blocks of reserves obtained by extrapolation beyond the contour of C1 blocks are calculated using the geological block method.

The reserves are calculated for the rock mass with the allocation of reserves in peat and seam.

In the blocks of balance reserves in the reservoir, the reserves of rich ores with a grade of 30 kg were calculated. per cube. m and more than conditional zircon in the sands.

The delineation of reserves was carried out in accordance with the established conditions. The reserves are classified into categories B, C1 and C2 and are divided into on-balance and off-balance.

The qualification of reserves by category was carried out in accordance with the density of the exploration network, hydrogeological knowledge and technological tests of the productive sands of the deposit. When assigning reserves to category B, an exploration grid of 200 by 100 m, C1-400 by 200 m,

C2-800 at 400 m. In addition, C2 category reserves were obtained by extrapolation beyond the C1 category reserves contour to a distance equal to half the exploration network distance adopted for this category.

0.6 kg/m. cubed.

The thicknesses (seam, peat and rock mass) of the workings were determined by summing up the thicknesses of the individual tested intervals.

The average content of useful components for the development was determined as a weighted average for the thickness of the tested intervals according to the formula:

Avg=М1С1+М2С2+……….М С

М1+М2+……+М

Where: M- thickness of the tested interval, m.

With- the content of the useful component in the sample

CONCLUSION.

As a result of geological prospecting and exploration work in the area of ​​the Tugan complex ilmenite of the zircon deposit, three large areas have been explored: Severny, Kuslovsko-Shiryaevsky and Chernorechensky.

A comprehensive study of the deposit made it possible, along with ore components, to investigate the non-metallic component of the placer and prove its great industrial significance.

As a result of the exploration of the Tuganskoye field, the following reserves were calculated.
