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 seeded with a finely divided magnetic particulate. The seeded slurry is then subjected to a magnetic field, to magnetically flocculate the contaminants and the magnetic particulate, and thereupon remove same.
