WATER REQUIREMENTS OF THE COPPER INDUSTRY By OBVILLB D. MUSSEY ABSTRACT The copper industry in 1955 used about 330 million gallons of water per day in the mining and manufacturing of primary copper. This amount is about 0.3 percent of the total estimated withdrawals of industrial water in the United States in 1955.

These groups of flotation cells work together to give a high total yield of the bulk ore, which is sent on to be thickened. Tailings (Gangue) Thickening / Dewatering.
