Fourteen domestic mines accounted for more than 95 percent of the 1.45 megagrams (Mg)Definitions International Copper Study Group,Copper is recovered from its sulphide ores by a dry extraction process in which the powdered and concentrated ore is roasted where necessary to drive off excess sulphur and smelted in a furnace to produce copper matte.
Copper extraction Wikipedia
Copper extraction refers to the methods used to obtaining copper from its ores. The conversion of copper consists of a series of chemical, physical, and electrochemical processes.Copper leaching from primary sulfides Options for ,The primary sulfide minerals of copper have been difficult to leach for the purpose of direct copper extraction. In particular, chalcopyrite has been observed to undergo a type of "passivation" under a variety of oxidative leaching conditions.
