Mining and processing Bentonite

Bentonite is a raw material present in many countries and mined in open pit quarries. Bentonite deposits are most often quite large, with lenticular beds, only a few meters deep. 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

Bentonite Processing schenckprocess

Bentonite Processing Simultaneous drying and grinding. Bentonite is a natural absorbent aluminium phyllosilicate clay in the Montmorillonite family that is formed by the decomposition of wind-borne volcanic ash. Due to the physical nature of this material, a Raymond® roller mill produces the best results at the usual fineness of grind. Bentonite usually contains 35 to 45% initial moisture in the deposit. This puts it well beyond the simultaneous drying

What is Bentonite? Industrial Minerals Association

Extracted bentonite is distinctly solid, even with a moisture content of approximately 30%. The material is initially crushed and, if necessary, activated with the addition of soda ash (Na2CO3). Bentonite is subsequently dried (air and/or forced drying) to reach a moisture content of approximately 15%. According to the final application, bentonite is either sieved (granular form) or milled (into powder and super fine powder form). For special applications, bentonite
