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.
Copper MiningandProcessing:ProcessingofCopper Ores...Copper processingis a complicatedprocessthat begins withminingof the ore (less than 1%copper) and ends with sheets of 99.99% purecopper…
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.
