Copper Ore Processing Methods

2017-04-11  Oxidized ores in which malachite, azurite, and chrysocolla are the predominant copper minerals that do not respond either to gravity or simple flotation methods. Sulfide-filming of the carbonates followed by flotation of the filmed minerals, or direct leaching followed by precipitation of the copper from the solution may be employed for such ores.
