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. To achieve better vertical separation of the gangue and concentrate, a horizontal screen is positioned above the propeller to equalize pressure and inhibit rotational flow in the upper portion of the vessel.
