Bentonit

We have been digging and processing bentonites since 1972.    

The complex of utility proprieties of bentonite depends on the mineral montmorillonite. The content of montmorillonite balances from 50 - 85 % (per cent).
   
The non-clay paris are represented by quartz, biotite and nonchangeable materials.

The average chemical analysis:


 SiO2 57 - 61 % 
 Al2O3 18 - 21 %
 Fe2O3 2 - 3 %
 FeO 0,1 - 0,5 %
 TiO2 0,2 - 0,3 %
CaO
1,9 - 2,6 %
 MgO 3,0 - 5,0 %
 K2O 0,4 - 1,0 %
 Na2O 0,2 - 0,7 %

The products of bentonite based on our raw material are noted for good absorption and reological proprieties. They include approximately 50 areas of utility in agriculture and industry. In the last time the significance of bentonite has highly increased with the building of ecological landfillings because of its good sealing proprieties.
