Electrowinning of Copper Using Rotating Cylinder Electrode ...

high-purity copper, copper is sent as a solute in an aqueous solution to the electrowinning plant. In this plant, an electric current is used to remove the copper from solution into flat sheets of metal. These flat sheets are 99.97% copper, which is the purest form of copper "in-dustrial wise" produced from any production process [1].

What Is Copper Electrowinning? - Sunwest Supply, Inc.

Copper electrowinning uses electric currents, anodes, and a process called leaching to extract the copper. This may be followed by electrorefining, which is used to purify the metals. Once the copper has been electrowon, it can be put to use.
