Chalcopyrite is the copper ore deposit of Falum, Sweden of Namagaland in South Africa. However, vast crystals or deposits occur in Ishiagu, Ebonyi State; South Eastern region of Nigeria (West Africa). High great chalcopyrite deposit can also be found in Baluba, East of Lusaka (Zambia).
(HLSX/EW), although only 10% of the primary production comes from this hydrometallurgical route . This process operates at ambient temperatures and the copper is dissolved to produce a copper sulphate solution through heap leaching, after which the copper is recovered through SXEW to produce pure copper cathode.

Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SXEW (solvent extraction/electrowinning).
