Copper Mining and Processing Processing of Copper Ores

The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different chemistries of the ore. Copper oxides are more abundant near the surface, but are considered low grade ore, with a lower concentration of copper.

These crystals may settle onto the bottom of the intrusion, concentrating ore minerals there. Chromite and magnetite are ore minerals that form in this way. Liquid immiscibility sulfide ores containing copper, nickel, or platinum may form from this process. As a magma changes, parts of it may separate from the main body of magma.

EXTRACTING METALS FROM SULFIDE ORES Electrochemical

Biochemical oxidation of the sulfide minerals releases the gold and allows it to be leached by the chemicals used in conventional gold leaching. Biochemical processes are being developed for the treatment of copper, nickel and cobalt sulfide ores and are expected to become the major method for recovery of these metals in the future.
