Abstract
A method for magnetically separating titaniferous discolorants from a crude kaolin clay. A dispersed aqueous slurry of the clay is formed and ferrimagnetic particles are thereupon spontaneously coflocculated with the titaniferous discolorants by seeding the slurry with a system of said particles. The system includes predominantly sub-micron size particles, and the particles further, have an isoelectric point in relation to that of the titaniferous discolorants to enable the spontaneous coflocculation. The slurry is thereupon passed through a porous ferromagnetic matrix in the presence of a magnetic field, to separate the coflocculated particles and discolorants at the matrix.
