Flow-thourgh magnetic separators for weakly-magnetic ores designed for superconducting magnets

Two flow-through model ore separators have been constructed and tested. Both separators use the magnetic field of a straight wire conductor which deflects magnetic particles in toward the conductor. Nonmagnetic gangue particles in the water slurry are deflected away by gravity in one case and by centrifugal forces in the other case. Tests have been conducted with synthetic ore slurries made up of carefully screened sizes of magnetite and silica. These tests show that separation does take place and that the theoretical separation time expected for ferromagnetic particles in a magnetic field is obtained.
