Abstract
A method for separating a metallic mineral from an ore containing same. 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 slurried mineral sought to be separated, 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.
