US4824431A - Centrifugal concentrator - Google Patents

Prior centrifugal concentrators for concentrating precious minerals use annular ribs or baffles to trap the precious minerals. Sand or magnetite tends to pack against such ribs, reducing the effectiveness of these devices. In the present invention, the inner surface of the rotating drum is free of obstacles, but forms three continuous zones, a migration zone, a retention zone and a lip zone.
