A mineral separator system providing for the removal of conductor and semiconductor materials from a pulp fluid containing nonconducting materials. Pairs of spaced magnet assemblies provide alternate or successive magnetic fields obliquely across a separation chamber through which the pulp fluid flows. Eddy currents set up in the conductors cause the conductor particles to migrate to a wall in accordance with the orientation of the magnetic field. Electrical stimulation of the semiconductors through the pulp fluid causes the semiconductors to have eddy currents induced therein.

A mineral separator system, comprising, in combination: at least one pair of opposed magnet assemblies and a pair of opposed walls connected to said magnet assemblies, said pair of walls and said at least one pair of magnet assemblies defining an elongated chamber having opposed inlet and outlet orifices, said at least one pair of opposed magnet assemblies having a plurality of alternately opposed, staggered magnetic poles generating alternately directed, generally parallel magnetic fields across said elongated chamber between said at least one pair of opposed magnet assemblies in directions oblique to the longitudinal axial center of said chamber; a source of pulp fluid containing a mixture of particles of non-conductive material and at least one type of conductive material, said particles of conductive material being capable of having eddy currents induced therein; means for pressurizing and passing said pulp fluid in a fluid stream through said inlet orifice and through said chamber through said laternately directed oblique magnetic fields, whereby eddy currents are induced in said particles of conductive material and lines of eddy force are generated in a direction substantially perpendicular to said oblique magnetic fields to retard said particles of conductive material and separate them from said particles of non-conductive material in said fluid stream; and means in said chamber for recovering said retarded particles of conductive material from said up fluid in said chamber before said pulp fluid passes through said outlet orifice.
