1. Introduction. Montmorillonite, a type of smectite mineral, is an aqueous aluminum silicate. It has a layered crystalline structure with the general chemical formula of (Na,Ca) 0.33 (Al, Mg) 2 (Si 4 O 10)(OH) 2 *nH 2 O. Rocks that mostly contain montmorillonite mineral are also called as bentonite. For this reason, sometimes the …Web
3. Crushing: Large pieces of bentonite are crushed by the crusher to the fineness that can enter the mill. 4.
