Bentonites
Characteristic of bentonites
North-Bohemian bentonites are mined and processed since 1953. In 1969 based on geological survey and evaluation of raw material resources our factory in Obrnice near Most was put in operation. Its production secured the whole of foundry industry in that time ČSFR...
Non-activated bentonites
Are produced of selectively exploited raw materials, homogenised, carefully dried and ground. BENTONIT 70 is especially suitable for activating of filling moulding mixtures...
Activated bentonites
Are produced from selectively exploited raw materials, homogenised, carefully dried and ground. Sodium carbonate is added to naturally damp mined bentonite in pug mills. The whole production process is carefully controlled and managed. Activated bentonites are suitable for preparation of pattern and unified moulding mixtures for all kinds of alloys...

Bentonites for foundry industry
Bentonites for building industry
Products of this series are oriented on use of rheological properties of bentonites by their selective exploitation and technological processing. Activated bentonites series G are specific for their high swelling ability, imperviousness of mixed and thickened layers, tixotropic suspensions for drilling and building purposes and sealing properties by maintenance and constructing of reservoirs, water dams and waste depots...
