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 factors.
as in all mining operations, the ore must usually be beneficiated (concentrated). the processing techniques depend on the nature of the ore. if the ore is primarily sulfide copper minerals (such as chalcopyrite), th · text under ccbysa licensecopper extraction chemistry bibliographies cite thissep , · intext (brown, n.d.) your bibliography brown, n.d. purification of copper by electrolysis metal extraction reduction of ores phytomining bioleaching raw materials electrode equations furnace smelter description of processs gcse igcse o level ks4 science chemistry revision notes revising.
