Abstract
A gravity-magnetic separator (10) for concentrating magnetic materials (28), particularly iron, is disclosed. The preferred separator is a cast-iron Humphreys spiral retrofitted with powerful rare earth magnets (22) beneath its separating surface (14), the magnets being sufficiently strong to overcome the shielding effect of the cast-iron spiral and induce a magnetic field at the separating surface of about 60 gauss to about 120 gauss. The resulting gravity-magnetic separator enhances the recovery of iron in a commercially significant way.
