Purecopper metalis generally produced from a multistageprocess, beginning with theminingand concentrating of low-grade ores containingcopper sulfide minerals, and followed by smelting and electrolytic refining to produce a purecopper cathode. An increasing share ofcopperis produced from acid leaching of oxidized ores.Click to view
Thecopper oxideminimum minerals are dissolved by the acid to give a bluecopperrich solution mainly ofcopper sulfate. This solution is tapped off from the bottom of the pad and placed into big tanks with steel plates an electrical current is passed from the tank to the steel which is then electroplated with purecopper.Click to view
Inrefining copper, the metal is melted down in a reverberatory furnace in a more or less oxidizing atmosphere and then further subjected to an oxidizing smelting in order to eliminate the common impurities, most of which have a stronger affinity for oxygen than hascopper.In these operations some of thecopperis oxidized to cuprous oxide and dissolved by the metal bath.Click to view
