ABSTRACT:
A process for filtering kaolin clay slurries in the presence of a filter aid which increases the percent solids in the filter cake, decreases the product solids in the waste filtrate, increases the rate of filtration, and yet does not interfere with redispersal of the filter cake after filtration. The process utilizes high molecular weight, highly anionic polyacrylic acid homopolymers or copolymers, or water soluble salts thereof, as filter aids for thickening and dewatering kaolin clay slurries. The flocculated clay may be redispersed after the separation process by normal means, such as the addition of low molecular weight anionic polymers with mixing.
