The electrorefining is at the heart of not only copper purifiion, but the production of sodium hydroxide and chlorine. In the electrolytic refining of copper, a thin sheet of highpurity Cu serves as the hode. The blister copper plates are taken and used as anodes in an electrolyte bath of copper sulfate, CuSO4, and sulfuric acid H2SO4.

Copper in Residue % Copper Extraction % 5% + 325 5% + 400 5% + 500 To further optimize copper extraction, compartment samples from the autoclave were taken to provide a leaching profile. The results from the compartment profiles are presented in figure 4.
