copper electrowinning process in details

Electrowinning GoldRefiningWikiUSA Copper electrowinning process Google Patents

The electrowinning of copper from acidic chloride leach solutions is difficult compared to the sulphate based process since chlorine often is produced at the anode One way to avoid the chlorine gas is to use a Copper I solution the anode process will turn Copper I chloride into Copper II chloride while metallic copper is deposited at the A process and apparatus for electrowinning a high purity copper from an aqueous pregnant liquor acid electrolyte at high efficiency and high current density in the presence of impuriti Electrolyte is circulated through an external loop system and upwardly between the anodes and cathod SOsub2 iron and acid are added to the electrolyte in the external loop to maintain an SOsub2
