Abstract
A gravity-magnetic ore separator for concentrating magnetic or weakly magnetic minerals having a relatively high specific gravity is disclosed. The ore separator utilizes codirectional magnetic and gravitational forces to achieve separation capabilities in excess of that which can be achieved using gravity forces alone. Typically, the gravity-magnetic ore separator is formed by retrofitting a conventional gravity separator such as a spiral, cone, pinched sluice, etc. with magnets so as to enhance the separation capability of the conventional gravitational ore separator. Means are provided to prevent build up of magnetic material on the surface over which the ore flows.
