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.
