Abstract
A method for magnetically beneficiating an ore by removing therefrom undesired metallic minerals of inherently low magnetic attractability. An aqueous dispersed slurry of the ore is formed, and the slurry is mixed with a system of transiently suspended ferrimagnetic particles of predominantly colloidal size. The particles are further characterized by an isoelectric point in relation to the mineral sought to be removed, such that the particles spontaneously co-flocculate with the mineral to seed same. The resultant seeded slurry is passed through a porous ferromagnetic matrix in the presence of a magnetic field, which separates the seeded mineral at the matrix, with the purified ore emerging from the matrix being recovered as product. This beneficiated product, i.e. now relatively free of the undesired species, can then (as appropriate) be further processed.
