Copper Mining and Extraction: Oxide Ores

The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.

A hydrometallurgical process for recovering copper from copper bearing ores or fractions, by a process of first wetting and sulfatizing the ore with controlled amounts of H 2 SO 4 and water, followed by acid curing and repulping to sulfatize a substantial portion of the copper in the ore. Also, the fine and coarse fractions can be classified, followed by pile leaching the coarse fraction

Eliminating Copper from Gold Ore

When reviewing Methods of Eliminating Copper from Gold Ores we see that several methods have been suggested to eliminate copper from ores prior to cyanidation. Preliminary extraction of the copper with sulphuric or sulphurous acids may be applicable to ores containing oxidized copper minerals such as malachite, azurite and chrysocolla but these acids have but little effect on sulphide copper
