In porphyry copper deposits, copper ore minerals are disseminated in igneous intrusions. Sedimenthosted stratabound copper deposits, in which copper is concentrated in layers in sedimentary rocks, account for about 20 percent of the world's identified copper resources. Globally, mines in these two deposit types produce about 12 million tons of copper per year.
In the most common hydrometallurgical process the ore is leached with ammonia or sulfuric acid to extract the copper. These processes can operate at atmospheric pressure or as pressure leach circuits. Copper is recovered from solution by electro winning – a process similar to electrolytic refining. The process is most commonly used for leaching low grade deposits in situ or as heaps.
