Since bentonite with improved rheological properties is required in engineering and drilling works, Ca-bentonites can be used as soda, etc. Activation with additives was mandatory. In addition, Ca-bentonites used as bleaching earth may need to be activated with acid to bring the bleaching power to the desired level. Since Ca-bentonite is much more common in our country, activation processes are inevitable, and activation processes with acid and additives such as CMC are applied. The general chemical formula of bentonite, a type of clay minerals; (Na,Ca) (Al,Mg) 6(Si4O10) 3(OH)6 nH2O.

Bentonite, volcanic ash, tuff and lavas formed by the chemical decomposition and decomposition of very small crystals of clay minerals (mainly montmorillonite), absorbing and swelling a lot of water, high ionization capacity, drilling mud, catalyst, paint, plastic, filler, etc. It is a commercial name given to an earthy mineral used in On the mineralogical and chemical composition of bentonite; There are different classifications according to industrial and engineering applications and similar usage areas. Here, the classification for industrial and engineering applications is given These are: – Wyoming product 85% 200 mesh bentonite bentonite suitable for casting, – Fuller earths treated with soda ash, suitable for casting, – Fuller earths treated with soda ash, suitable for engineering works, -OCMA special product, -API special product, In addition, a bentonite product used as ‘cat litter’ and ‘white bentonite’ are also included in this classification.
