Commercial Importance Of Bentonite Mineral Processing

Bentonite Bentonite is clay consisting of smectite minerals, in particular montmorillonite. Bentonite has exchangeable Na, Ca, or Mg cations, and exhibits far greater ion-exchange worldwide capacity than any other mineral except for zeolite. Na-bentonite has high swelling ca-pacity and ca-bentonite has a relatively low swelling capacity.
