The copperbearing aqueous phase is advanced to the electrowinning (EW) stage of the process while the barren organic phase is returned to the extraction stage of the process. In the electrowinning stage of the process the copper is reduced electrochemically from copper sulfate in solution to a metallic copper cathode.
Electrowinning Copper. In the electrowinning stage of copper extraction, the solution containing the copper ions is pumped through a series of tanks. Suspended in these tanks are sheets of lead alloy (anodes) alternating with cathodes made of either thin copper starter sheets or stainless steel blanks.
