What is Bentonite? Industrial Minerals Association
Bentonite deposits are normally exploited by quarrying Extracted bentonite is distinctly solid, even with a moisture content of approximately 30% The material is initially crushed and, if necessary, activated with the addition of soda ash (Na2CO3) Bentonite is subsequently dried (air and/or forced drying) to reach a moisture content ofBentonite deposits of Kimolos Island, Aegean, Greece were investigated in order to determine their physical and chemical properties Testing included measurement of CEC (cation exchange capacity), swelling capacity, pH, rheological properties and some important foundry properties including green and dry compression strength, shatter index, wet tensile strength, compactability and permeabilityPhysical and chemical properties of some bentonite
