Our Company has mine and processing certificates of the two best bentonite deposits in Russia with the capacity to produce over 35 million tons. And also one of the best high quality deposit in the world in Azerbaijan Republic with the capacity about 86 million tons:
The deposit 10-th Hutor located in Khakas republic.
The deposit 10-th Hutor located in Khakas republic.
The deposit Dash-Salakhlinskoe located in Azerbaijan Republic.

To guarantee the stable quality of the mining material every deposit is provided with geotechnical mapping. The exploring is constantly operating.

Bentonite clays mining from 10-th Hutor and Ziryanskoye deposits contain from 70% to 80% montmorillonite, with exchange interaction containing calcium and magnesium cations. Moisture bentonite is activated by soda ash, that means that calcium and magnesium cations are replaced by sodium cations, after that bentonite properties are near to natural sodium bentonite properties. Natural sodium bentonite clays mining from Dash-Salakhlinskoe deposit contain not less than 85% montmorillonite.

Chemical composition of bentonite clay 10-th Hutor, Ziryanskoe and Dash-Salakhlinskoe are presented in the following table.
