Ground talc

Shabrovski talc deposit and the factory are situated 27 km to the south of Ekaterinburg. Quarrying was begun in 1931 (see photo)

At present JSC "Shabrovski Group of Talcmines" is the biggest producer of talc production for all industries of the Russian Federation and CIS countries. All our products are made by crushing talc flotated concentrates and talc magnesites of Shabrovski deposit which we own.

Talc is a magnesium hydrous silicate (3 MgO 4 SiO2 H2O; MgO - 31.74%; 4SiO2 - 63.5%; H2O - 4.8%), its hardness according to the Moos scale is 1 (the softest mineral), its relative density is 2,7 - 2,8, it has low thermal and electrical conduction, its melting temperature is 1530 С°, it has high acidity (it is totally dissolved only in HF), the concentration of hydrogen ions in aqueous soliquid (PH) 8,5 is 10,0; the material is hydrophobic. The other name for talc widely used in technical literature is STEATITE.

Ore containing talc is mined in the quarries of the industrial complex. The ore is crushed, is then refined by means of flotation (depending on the talk sort), undergoes the thickening procedure, is packaged and after that final produce is shipped to the customer.

The characteristic feature and unique technology of our production process is the FLOTATION (enhancement) of the talc ore. Thanks to this method deeper refinement of the original raw material is achieved as well as stable homogeneous physical-chemical composition of the final produce. Talc homogeneity and degree of refinement have crucial influence on the quality of its applications in different industries. That is the reason why the majority of enterprises committed to the high quality of their production are the customers of JSC "Shabrovski Group of Talcmines".

We have hygienic, quality and radioactive safety certificates for the whole range of our production.

LIST OF PRODUCTS AND MAIN SPHERES OF ITS APPLICATION

Below you will find kinds and sorts of goods produced by "Shabrovski Group of Talcmines". A list of applications of every kind of talc and microtalc is given in the column 'Sphere of application'. As the volume of talc consumption is constantly increasing and ways of its application are expanding, the list of ways of applications is just exemplary, describing the most widely-spread kinds of application only. To identify the sort of talc suitable for your production process use physical-chemical parameters and consult our specialists(see Contacts).

1. Talk and microtalk (given in parameter quality ascending order).

№ п/п	Name	Brand	GOST/TU	Main spheres of application and properties
1	Ground Talc magnesite	TMN	GOST 21235-75	Production of: - roofing and hydro-insulating materials (and powder), - pesticides, insecticides
2		TMP		Production of: - pesticides, insecticides
3	Ceramic talc	ТМК-27	GOST 21234-75	Production of: - stoneware, - welding electrodes, - in metal casting (antisticking covering). It possesses an ability to give a mechanically durable crock after thermal treatment, which characteristic features are low moisture capacity, insignificant shrinkage, chemical endurance, and low thermal and electrical conduction, fire resistance.
4		ТМК-28
5	Rubber talc	TRPV	GOST 19729-74	Production of: - rubber products (filler and powder), - plastics (filler), - automobile tires (filler and powder), - ceramics (filler for refractories).
6		TRPN
7	Cable talc	TK-1	GOST 13145-67	Production of: - the same as for TRPN and TRPV, - cable rubber (filler), - building and automobile paste fillers and putties (filler). This product is characterized by low electrical conduction.
8	Enriched talc	ТМ-О	TU 21-25-161-75	A more qualitative analogue of ТК-1. Production of: - the same as for ТК-1, - vanish and paint products, - chemical industry. This product can hold on its surface as on a chemically inert base different other substances, e.g. pigments.
9	Food talc	А-2	TU 21-25-217-78	Production of: - ceramics - glaze (enamel) for ceramic industry, - confectionery (powder for packing materials), - medicine (powder, filler), - chemical industry.
10		А-1
11	Microtalc	МТ-К	GOST 19284-79	Production of: - vanish and paint (filler for enamels, paints, primers, paste fillers and putties), - slate pencils, - paper, - glaze (enamel) for ceramic industry, - electricity insulating ceramics, - foamed plastics, polystyrene (as a work material for production of talk concentrate used for their production).
12		MT-GHM

The main consumers of talc and microtalc in Russia and CIS countries are plants and factories producing rubber, caoutchouc, plastics, vanish and paint, roofing, ceramics (ceramics, porcelain, faience) metallurgical plants, plants producing electrodes, tires, insulating materials, confectionery, pulp and paper, petrochemical, ore mining and processing enterprises, automobile and tractor producing plants, as well as industrial complexes producing building materials, household and industrial chemical goods: clues, putties, insecticides, pesticides, fertilizers, etc., agriculture and road building enterprises. However, this is not the whole range of industries consuming talc as at the present moment the sphere of its application is constantly modified and expanded

2. Fertilizers

Magnesite fertiliser	TU 2189-00281950-001-99

Description:
Magnesite is a natural magnesium fertilizer. It is an effective long-active fertilizer for acidic soils with low concentration of magnesium. It is characterized by high neutralizing ability, overbalancing the effect of limestone dust. It is used together with other fertilizers and soil liming. When magnesite is used, harvest increase is 20-40%. It contains soluble MgO - more than 20%, microelements: cobalt, copper, zinc, manganese, iron, as well as talk as a soil ripper. Magnesite is an equivalent substitute for magnesium sulfate, but in comparison to it, it does not acidate, but neutralizes the soil. When used, it increases preservation and quality of cultivated plants.

3. Mineral powder for road concrete mixes

Mineral powder		TU - 5716 - 008 - 00261950 - 2002

Description:
mineral powder is used in production of road concrete mixes of different categories. As compared to all the previously used powders it has the following advantages: its more hydrophobic, is characterized by high bitumen absorption that allows its even distribution in bitumen. Application of this produce leads to higher density and homogeneity of asphalt concrete; it prevents moisture penetration, decreases water saturation that has a positive effect on the automobile road working life. Its usage in the asphalt concrete with the presence of clay particles is especially important. However this is not a complete list of mineral powder advantages.
