Basic Material

 

The Eleninskoe deposit has been mined since 2002. Its explored reserves is valued at 6 000 000 tons. The quarry is situated 250 km to the South from Chelyabinsk, not far from Eleninka village. The mining of the deposit is opencast. Extracted marble goes to a crashing unit, where it is crushed and classified at fractions of 2.5-20 mm and sand of 2.5-0 mm.

 

The basic material for products of our company is high-quality white marble of this deposit.

 

The marble from Eleninskoe deposit is unique because of its special features, which are:

  • clearly marked crystalline structure;

  • high content of calcium carbonate CaCO3 (97%);

  • increased strength of a crystal grain;

  • high refraction;

  • low content of coloring iron oxide, manganese oxide, titanium oxide, and as a result high whiteness (from 90 to 97 depending on the fraction);

  • low content of water-soluble salts;

  • good solubility in mineral acids;

  • high stability in ultraviolet radiation.

Ecological Characteristics of Marble

 

Sample of the ground marble of Eleninskoe deposit were tested in the laboratory in State Sanitary Supervision in Chelyabinsk. According to the tests the marble is the material of class I and can be used in building without restriction. Our products and basic material are ecologically safe.
