Historically, the most abundant source of copper has been chalcopyrite (CuFeS2). Copper can be produced through pyrometallurgical or hydrometallurgical processes. Several new pyrometallurgical processes have emerged over the years which improve upon the traditional roasting, smelting and converting process. Hydrometallurgical processing of copper concentrates has seen renewed interest since the success of heap leaching along with the commercial development of efficient solvent extraction and electrowinning technology. The most common hydrometallurgical process involves the extraction of copper by leaching the ore with ammonia or sulphuric acid.
Copper is commonly used in electrical equipment such as wiring and motors. This is because copper has excellent heat and electrical conductive
