Microstructure of Bentonite in Iron Ore Green Pellets

Introduction. Bentonite is an impure mineral containing mostly montmorillonite, a clay of the smectite family. Because of its versatile properties, bentonite is used in many industrial applications, e.g., in drilling muds, as a foundry bond clay, and as a sealant in irrigation ditches and radioactive waste repositories (Murray, Reference Murray 1991; Pusch & Yong, Reference Pusch and Yong 2005).

Bentonite - an overview | ScienceDirect Topics

Bentonite is an off-white montmorillonite clay formed from altered volcanic ash. It has a sheet-silicate structure and is especially notable for the way in which it absorbs and loses water and for its base-exchange properties. Sodic bentonite can absorb up to 10 times its own weight in water and can swell to 18 times its dry volume.
