Learn About Bentonite Mining in Wyoming

Mining & Processing. Bentonite is surface mined through a process called back-casting where reclamation is performed by filling the mining pits with soils from subsequent pits while the mine is in production. Typically the topsoil layer is about 30 inches deep, which is removed using heavy equipment.

Mining and processing Bentonite

Mining and processing. 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.

Bentonite exporation and mining Clariant Ltd.

While bentonite per se is abundant on earth, careful selection of the right bentonites for the individual applications is a crucial part of ensuring uninterrupted supply. To this end our own exploration team of geologists, mineralogists and mining engineers travels the world to find suitable deposits for our customers’ needs.

Bentonite mineral extraction –Surface mining technique

Wyoming's Bentonite industry produced over 4.0 million tons of bentonite in 1999, with 644 mine and mill employees, and 240 contractor employees. Exploration for new bentonite beds is normally gifted with auger bit drilling. Once the auger drill stem reaches the soft bentonite it sinks very fast, which indicates to the driller that bentonite
