Copper Ore Processing Methods

Oxidized ores in which malachite, azurite, and chrysocolla are the predominantcopper mineralsthat 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.

Predominant minerals in the oxide ore zone are oxidized minerals of lead andzinc(descloizite,cerussite,willemite,smithsonite) with a minor amount of sulfides, while the sulfide ore zone contains sulfide minerals (galenaandsphalerite) predominantly. As maingangue minerals,calcite,dolomite, and some silicates are present in both ore types.

Flotation of the ore from the sulphide zone is also negatively affected by the presence of the copper enriched ore. Therefore, ore blending for processing plant and the determination of surface oxidation of the sulphide minerals are very important for a steady state operation in the process plant.
