an electrolytic recovery in a cell with two rotating discs on the copper deposition rate and quality of metals was studied. An electrolytic recovery represents pretreatment of wastewater for the subsequent treatment in a cascade line.

Copper electrorefining entails electrochemically dissolving copper from impure copper anodes into an electrolyte containing CuSO4 and H2SO4, and selectively .
Electrolysis of copper transfers copper atoms from an impure copper anode to a pure copper cathode, leaving the impurities behind. Unrefined copper is about 99 % pure. It contains traces of metals such as Fe, Zn, Ag, Au, and Pt. The purity can be increased to % by electrolytic refining in a cell similar to that shown below.
