Summary: | A method for magnetic separation of materials wherein the materials are ground to provide a mixture of fine particles of more- and less-magnetic materials which may include paramagnetic material and diamagnetic material. Discrete bodies of highly magnetizable material are introduced to a magnetic field of high intensity and thereby become a closely consolidated mass of bodies having interstitial pores extended through the mass in all directions. The mixed particles are caused to flow through the pores and the less-magnetic particles are separated from the more-magnetic particles and the mass of bodies in the magnetic field. The more-magnetic particles are separated from the bodies by moving the mass of bodies out of the magnetic field and by demagnetizing them so that they tumble freely and by washing or otherwise removing the particles from the bodies as they tumble after leaving the closely consolidated mass. |
