ABSTRACT:
A mineral concentrator, including a main support base interconnected to a deck by a flexible support and an oscillator assembly, for recovery of free minerals from a mixture of screened raw materials is disclosed. A symmetrical deck is divided in equal parts by a longitudinal center line plane and includes two sloping surfaces extending laterally and longitudinally downwardly and away from a feed end of said deck. Water and raw material are continuously supplied at the feed end of said deck and moved along the sloping surfaces. First riffles are defined in association with the sloping surfaces and generally perpendicularly to a fall line. The first riffles intercept said raw material and terminate at a point allowing the water and entrained waste materials to fall to the side of the deck for removal from troughs positioned thereat. Relatively longer, narrower and shallower second riffles are interspersed parallel to the first riffles for carrying relatively denser material toward the concentrate end of the deck. Waste material is washed away from the relatively denser material. A second water supply establishes a film which covers the sloping surfaces and in which the raw material is entrained. The second riffles terminate and transfer concentrate material to relatively wider and deeper third riffles, which are also parallel to the first and second riffles, further separation of less dense minerals taking place at the transfer. The third riffles communicate with fourth riffles, parallel to said center line, which fourth riffles carry said concentrate to a discharge or collection trough.
