Flotation of mixed copper oxide and sulphide minerals
AM28 successfully recovered malachite and minor azurite, which were present in Minto's oxide ore. The sulphide recovery for the blend composite was not adversely affected. Lower copper sulphide recovery is one of the main concerns for many operations in blending oxide ores with their main sulphide ores, and such a loss can be …

The Extraction of Copper
The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.
