Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (water-based) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning. Heap Leachingis the process of using percolating …

This stage of smelting produces matte or copper matte, a copper-enriched combination of copper, iron, and sulfur. The objective of the matte smelting step is to remove as much iron, sulfur, and gangue minerals (such as silica, magnesia, alumina, and limestone) as possible while reducing copper loss.

Sulphide ores are usually first concentrated using froth flotation to recover the copper host minerals, such as chalcopyrite, bornite or chalcocite from the gangue minerals. The resulting copper sulphide concentrate is then smelted to produce the final copper product.

These methods exploit the differences in the physical and chemical properties of copper sulfide minerals and gangue materials. Roasting. The concentrated copper sulfide ore is then roasted in a furnace to convert the copper sulfides (usually copper pyrites, CuFeS2) into copper oxide (Cu2O) and sulfur dioxide (SO2). The chemical reaction is as ...

The slurry is a mix of valuable copper ore minerals and "worthless" rock, called gangue (pronounced "gang"). The slurry is placed in a tank and a process called froth floatation is used to separate the copper minerals from the gangue.
