The discharge from the tube mill is first passed through a 4-mesh 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 " Sub-A" Flotation Cell, from which 60% of the gold and silver in the feed is removed as a concentrate.
