Copper Electrorefining

Electrowinning copper key concepts electrowinning refers to the process of using electrolysis to extract a metallic element from the compounds in its ore copper occurs on earth both as native copper the uncombined element cu and in ores copper compounds or mixtures of compounds from which copper metal can be extracted profitably.
