Bentonite - WikipediaBentonite usually forms from weathering of volcanic ash, most often in the presence of water. However, the term bentonite, as well as a similar clay called tonstein, has been used to describe clay beds of uncertain origin. For industrial purposes, two main classes of bentonite exist: sodium and calcium bentonite.Industrial Clays Case Study - Whitemud Resources Inc.Bentonite. 5. Palygorskite - Sepiolite. 7. Industrial Clays. Kaolin. Kaolin is a soft, white plastic clay consisting mainly of the mineral kaolinite which is a hydrated aluminum silicate . and chemical properties of kaolin has led to it=s extensive use as filler, extender, paper . refractory, catalyst, cement, and fiber glass industries.
