Copper Purification Process - Electrolytic Copper Refining Plant
The electrorefining is at the heart of not only copper purification, but the production of sodium hydroxide and chlorine. In the electrolytic refining of copper, a thin sheet of high-purity Cu serves as the cathode. The blister copper plates are taken and used as anodes in an electrolyte bath of copper sulfate, CuSO4, and sulfuric acid H2SO4.

The electrolyte is copper sulphate solution. The copper atoms at the anode lose two electrons each and become copper ions. These dissolve in the solution and migrate to the cathode where they are deposited as pure copper. Therefore the impure anode loses mass and the pure cathode gains mass. The insoluble impurities from the anode collect ...
