CA 2167340

A process is disclosed for the production of a blended smectite clay with enhanced rheology, particle size restriction and reduced abrasion characteristics which is useful for the coating of paper. The process comprises slurrying of a predominantly sodium smectite clay, slurrying a predominantly calcium smectite clay, degritting of the clay slurries to remove coarse grained impurities, removing a substantial portion of the undesirable soluble salts from the clay slurries, fractionating the clay slurries to control particle size of the smectite clays in the slurry and blending together the predominantly sodium smectite clay slurry with the predominantly calcium smectite clay slurry to form a blended clay slurry.
