Centrifuge processing of high-solids clay

摘要

Method of removing coarse materials and chemical and mineral impurities from clay in order to produce a purified high solids suspension of said clay which method involves mixing a crude clay with water and a dispersing agent to form a high solids slurry; subjecting said slurry to intense centrifugal forces for a short period of time; separating said coarse material and said chemical and mineral impurities; and recovering the suspended clay as a fine fraction having a reduced content of coarse material and impurities.
