Treatment of Mixed Sulfide Oxide Ores of Copper

Many ores containing oxide copper are hard to settle or filter at flotation fineness as they come from the mine and they all are much worse after contact with acid. Settling areas of 40 or 50 sq. ft. per ton-day are not uncommon; for a 5000-ton plant, a small-scale operation, this would mean thickeners 400 or 500 ft. in diameter.
