COPPER ELECTROWINNING: THEORETICAL AND PRACTICAL DESIGN 213 Introduction The electrowinning of copper ions derived from leaching, or solvent extraction is a significant contributor to the global copper commodity supply. The process of electrolysis for copper was first developed in the late 19th century and despite numerous advancements in technology the
Copper electrowinning is the recovery of copper metal onto the cathode from electrolyte. The electrolyte may be the leach solution or the purified solution from solvent extraction. The copper electrowinning cell house using the conventional cells has many cells.
De Noras solution for copper electrowinning includes latest generation energy saving electrocatalytic coating and a patented engineered titanium structure with breakthrough dendrite mitigation system for self protection against short circuits. The development of a monitoring system completes the package.

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 alternating with cathodes made of either thin copper starter sheets or stainless steel blanks.
