electrowinning of copper is a vision of the future in the present. This paper attempts to demonstrate that copper electrowinning based on reactive electrodialysis can be a good alternative process compared to the present electrowinning process in terms of specific energy, cell voltage, and current density. 2. Experimental part
Electrowinning is the recovery of metals, such as gold and silver, from solution by passing a current through the solution. Electrons from the current chemically reduce the gold and/or silver ions, to form a solid metal compound on the cathode.
With emew electrowinning, the electrolyte is circulated rapidly past the anode and cathode at a very high flow rate, significantly enhancing mass transfer and allowing for improvements in efficiency and recovery. "Novel electrochemical cell designs are emerging as alternative process units for various applications in industry.
