Abstract
A method for magnetically separating discoloring contaminants of low magnetic attractability from a crude kaolin clay containing said contaminants. A dispersed aqueous slurry of the clay is admixed with a finely divided magnetic particulate. The slurry is thereupon passed through a porous, ferromagnetic matrix in the presence of an applied magnetic field, whereby contaminants seeded by the particulate are separated from the slurry.
