  • 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 lowgrade ore, with a lower concentration of copper.
