PROCESS FLOWSHEET DESCRIPTION: Gold Mineral Jig in grinding circuit (ball mill discharge) at center of gravity concentration plant.

ORE TREATED: Various oxide and nonmetallic minerals not now recoverable by flotation.

ADVANTAGES: Where fine grinding is necessary before gravity concentration, high tailing losses are unavoidable as slimed mineral is not efficiently concentrated and recovered by gravity methods. The flowsheet shown, with the Mineral Jig in the closed grinding circuit, has greatly increased recoveries where used.

For being totally chemical-free, this flowsheet brings you gold tailings processing equipment requirements to a minimum or nil.

A high percentage of the minerals is recovered when freed and at a coarse mesh. Sliming of this fraction, with its resulting losses, is avoided.

PROCESSING COMMENTS: Marketing of concentrates is often simplified through the production of a coarser and more granular concentrate product.
