The discharge from the tube mill is first passed through a 4mesh screen to separate out coarse material, which is laundered direct to the classifier. The remainder of the pulp, diluted to give a W/S ratio of 1/1, passes to a Denver " SubA" Flotation Cell, from which 60% of the gold and silver in the feed is removed as a concentrate.

Gold or silver are next removed from the stripping solution by electrowinning. Typical electrowinning cells contain a stainless steel anode plus a stainless steel wool cathode for plating the metal. The steel wool cathode is usually packed to a density of 1 lb/ft (16 kg/m ) and provides a cathode surface area of 10 ft/lb (2 m /kg).

The gold anodes are made exclusively from the gold from the silvercells, which assays about 875 thouhs gold, from 100 to 125 thouhs silver, and a small amount of base metals. This gives, in the first cells, cathodes about fine, which, on being retreated in the second set of cells, produce gold about fine.
