The performance of a gravity separator is enhanced by providing a magnetic material on the separation surface of the gravity separator. A magnetically enhanced gravity concentration/separation apparatus is provided for enhancing separation of a target feed material from remaining feed materials in a feed mixture having a transport medium and feed materials which comprise the target feed material and the remaining feed materials. The target feed material is magnetic and generally has a higher specific gravity than any magnetic feed materials contained in the remaining feed materials. The separating apparatus comprises a gravity separator including a separation surface on which to flow the feed mixture. The separation surface includes a magnetic separator material thereon to provide a magnetic field producing a sufficiently high magnetic attraction to enhance separation of the target feed material from the remaining feed materials in the feed mixture as the feed mixture flows over the separation surface carrying the remaining materials past the separation surface. The magnetic attraction of the magnetic field provided by the magnetic separator material on the separation surface is sufficiently low to at least substantially avoid accumulating magnetic feed materials contained in the feed mixture on the separation surface. |
