Electrowinning of copper in a lab scale

Electrowinning is an electrometallurgical process whereby copper that is is led to electrowinning cells similar to small pools that contain anodes and The copper electrowinning cell contains many cathodes and the same number 1 It is been recognized also that small addition of cobalt to copper electrolyte May 23 Abstract This work describes the design and optimization of a laboratory scale copper electrowinning cell based on reactive electrodialysis that
