1. An apparatus for separating non-magnetic mineral values from a source material containing magnetic material and non-magnetic material, the apparatus comprising:
- a frame;
a non-magnetic material collection channel mounted to the frame for collecting non-magnetic material;
a feed mechanism for supplying the source material to the collection channel;
retaining members mounted within the collection channel to retain the collected non-magnetic material;
a fluid connection on the collection channel configured to connect a source of fluid to the collection channel, the fluid transporting the source material fed from the feed mechanism along the retaining members for retaining non-magnetic material and flushing the magnetic material contained in the source material away from the retaining members; and
a magnetic separation assembly mounted adjacent the collection channel for exerting magnetic fields on the source material transported by the fluid to repel the non-magnetic material in the source material against a flow of the fluid transporting the source material to assist collection and retaining of the non-magnetic material in the retaining members.

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.
