  • Difference Between Kaolin And Bentonite Clay Compare

    Difference Between Kaolin And Bentonite Clay Compare

    Aug 21, 2018 The key difference between kaolin and bentonite clay is that the kaolin clay forms as a result of weathering of aluminium silicate minerals such as feldspar whereas the bentonite clay forms from volcanic ash in the presence of water. Kaolin refers to a mineral that is rich with kaolinite. Both kaolinite and bentonite are clay types. And, both these minerals have many different applications ...
