Copper extraction Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores The conversion of copper consists of a series of physical and electrochemical processes Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factorsSometimes, however, further refining is required if ultrahigh purity metals are to be produced The primary types of metal recovery processes are electrolysis, gaseous reduction, and precipitation For example, a major target of hydrometallurgy is copper, which is conveniently obtained by electrolysisHydrometallurgy Wikipedia20102014  Copper in our Electrical World part 3 Copper mining and processing How copper is extracted, crushed, and sent to the two major processing methods We use small cameras to follow the path of copper ore as it is processed into pure copper Pyro and Hydrometallurgical Copper Processing P3
