ABSTRACT OF THE DISCLOSURE The apparatus includes a fluid-tight housing oscillated about a vertical axis, the housing containing a central deflector separating the housing into an upper chamber and a lower chamber. Baffles are provided in both chambers, above and below the deflector. The upper baffle directs the incoming slurry radially outwardly in a torical path, throwing the particulate material toward the periphery of a housing in the first separation zone the particulate material passing in a gravity induced flow, through the annular passageway into the lower hopper where the relatively lighter and heavier constituents are then separated and separately discharged from the housing. A ring dam formed in the second baffle provides a recess into which the lighter constituents overflow where they are reunited with the liquid flow path and thus discharged from the housing. An aspirator removes air automatically from the top of the chamber. The method carried out by the apparatus is claimed. In a second embodiment the slurry is introduced tangential in the upper chamber and radial paddles or baffles arrest the whirlpool thus created, so that during the first portion of operation the slurry is subjected to centrifugal action and subsequently to settling action. In other forms of the invention, recirculating closed systems are provided for re- circulating the fluid medium. Also, the flow rates of the fluids and solids or particulates are independently adjustable by various means. The slurry is formed from fluid particulate material. Either gas (air) or liquid (water) is used as the fluid medium and finely divided solids such as gold ore is used as the particulate material.
