Abstract
Apparatus is provided for separating non-magnetic mineral values from a source containing magnetic material and non magnetic material. The apparatus includes first and second conveyers in overlying relation which counter-rotate relative to one another. One of the conveyers includes a magnetic assembly which cooperates with paddles on the upper conveyer to progressively isolate values from magnetic material. Multiple stages are provided for intermittent magnetic interactions such that the non-magnetic materials are effectively isolated from the magnetic materials.

25. A method of wet separation of non-magnetic metal values from a source material containing non-magnetic material and magnetic material, the method comprising the steps of:
-
providing a non-magnetic material collection channel for collecting non-magnetic material;
feeding the source material to the collection channel;
treating the source material with a fluid in the collection channel to transport the source material along a retaining member for retaining non-magnetic material, the fluid flushing materials other than the non-magnetic metal values away from the retaining member; and
providing a magnetic separation assembly adjacent the collection channel, the assembly having discrete sections of magnets, the sections of magnets in spaced longitudinal relation forming alternating areas of presence and absence of a magnetic field for permitting the magnetic fields to intermittently act on the source material to progressively separate the magnetic material from the non-magnetic material during transportation along the retaining member, the non-magnetic material carried by the fluid being efficiently collected and retained in the retaining member in the absence of magnetic material.
