ABSTRACT:
Severed metal bearing ore is placed in a vessel having a water inlet at the bottom and an outlet at the top. A propeller causes water to flow upwardly through the vessel and to be discharged through the outlet carrying gangue with it. Concentrate, which is heavier because it contains the metal to be recovered, does not rise to the level of the outlet and therefore remains in the vessel. A member, which can be floated on the top surface of the water, inhibits turbulence and suppresses the formation of a vortex, thereby contributing to the formation of a calm water region at the top of the vessel for improved separation. Water turbulence can be further inhibited by a screen placed across the vessel between the propeller and the floating member.
