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.

27. A separation apparatus for separating a target material from a source material, the apparatus comprising:
-
a carrier for transporting the source material along a predetermined path; and
a magnetic field generator including a plurality of magnets for forming alternating areas of presence and absence of a magnetic field along the predetermined path so that the magnetic fields intermittently act on the source material transported by the carrier to progressively separate the target material from the source material, the strength of the magnetic fields being such that not only magnetic materials in the source material are affected as being attracted, but also conductive non-magnetic materials in the source material are affected by virtue of induction, causing repulsion of the conductive non-magnetic materials away from the magnetic field. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
