  • 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. Once the bentonite is removed, it is cleaned and then tested to confirm the grade. It is then

  • Using Bentonite Mud and Managing Mud Pits

    Using Bentonite and the Mud Pits. Once the bentonite mud has been fully hydrated, a portion of the very thick mud that has been mixed in a 55-gallon drum (or large trash can) may be used to coat the sides and seal the bottom of the mud pits if the soil is very porous. Using bentonite mud in this way is better than lining the pits with plastic or some other material. This can be done as the mud
