ABSTRACT:
There is disclosed a method and apparatus for recovering small particles of gold or platinum from a slurry by feeding the slurry onto a layer of mercury which is flowing downwardly along a generally conical, downwardly converging inner wall of a housing. The housing is rotated about the vertical axis of the conical wall at a speed which induces particles to settle out or amalgamate with the layer of mercury and causes the remainder of the slurry to move upwardly over the mercury layer and out of the housing. Upon collection and separation of the particles therefrom, the mercury is returned to the housing for resupply to the inner wall thereof so as to maintain a continuous layer of mercury.
