Bentonite
Bentonite is a naturally occurring plastic clay that was first found in about 1890 in upper cretaceous tuff near Fort Benton, Montana. It is a very useful and versatile mineral that is found in a wide variety of products and services. Therefore, bentonite is often called "the clay of a thousand uses."Bentonite is created from the alteration of volcanic ash. …

Bentonite processing
Overall. Bentonite Processing is quite simple, though, because of its high affinity to absorb moisture; special attention is needed so as to choose the appropriate size reduction device. If the raw bentonite has a considerable moisture content, a primary size reduction in a crusher that employs the effect of comminution might not be effective.
Mining and processing
Bentonite production process features ore mining, sodium activation – if required -, drying, and milling. Sodium activation is performed to convert calcium bentonite to sodium bentonite, in which calcium ions are exchanged for sodium carbonate. Through drying, bentonite natural moisture content of about 25-35% is reduced. ...
