ABSTRACT:
Apparatus is provided to separate heavier metal particles from lighter particles gangue in a fluidic medium by gravity and fluid flow. A vertical container provides a lower fluid input chamber that communicates through a medial structure providing a plate defining a plurality of valve ports, a screen, and a plate defining a plurality of holes to an upper chamber carrying particulate material to be beneficiated. Pressurized water flows upwardly through the medial structure to separate more dense metal bearing particles in the medial structure and gangue exits from a central orifice defined in the medial portion of the separating structure. The apparatus uses small amounts of water which may be recycled. The beneficiator is unusually efficient in recovering particulate gold from alluvial sands.
