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.

46. An apparatus for separating non-magnetic substances from a source material containing magnetic material and non-magnetic material, comprising:
-
a plurality of magnetic separating stations longitudinally spaced apart to provide alternating areas of a strong magnetic field and the absence of a strong magnetic field;
a conveyer for moving the source material beneath the magnetic separating stations such that at a magnetic separating station magnetic material within the source material is attracted away form the conveyer to the magnetic station and non-magnetic material is not attracted to the magnetic station and remains on the conveyer, the conveyer having a discharge end;
a scraper for periodically separating the magnetic material from each of the magnetic stations such that the magnetic material falls onto the conveyer to form a layer of the magnetic material in areas of the conveyer transporting the non-magnetic material thereon, wherein each downstream magnetic separating station acts on the source material on the conveyer to further separate the magnetic material from the non-magnetic material;
a non-magnetic material receptacle located proximate the discharge end and a magnetic material receptacle located proximate the discharge end; and
a discharge separating device located proximate the discharge end to cause substantially only the separated non-magnetic material to be discharged into the non-magnetic material receptacle and substantially only the separated magnetic material to be discharged into the magnetic material receptacle. - View Dependent Claims (47, 48, 49, 50, 51)

52. A method for separating non-magnetic substances from a source material containing magnetic material and non-magnetic material, the method comprising the steps of:
-
providing alternating areas of a strong magnetic field and the absence of a strong magnetic field via a plurality of magnetic separating stations longitudinally spaced apart;
moving the source material via a conveyer located beneath the magnetic separating stations such that at a magnetic separating station magnetic material within the source material is attracted away form the conveyer to the magnetic station and non-magnetic material is not attracted to the magnetic station and remains on the conveyer;
periodically scraping and separating the magnetic material from each of the magnetic stations such that the magnetic material falls onto the conveyer to form a layer of the magnetic material in areas of the conveyer transporting the non-magnetic material thereon, wherein each downstream magnetic separating station acts on the source material on the conveyer to further separate the magnetic material from the non-magnetic material;
discharging substantially only the separated non-magnetic material into a non-magnetic material receptacle and discharging substantially only the separated magnetic material into a magnetic material receptacle. - View Dependent Claims (53, 54, 55, 56, 57)
