METALLURGY OF COPPER-EXTRACTION OF COPPER-BLISTER

The electrolyte is copper sulphate (CuSO4) mixed with a little amount of H2SO4 to increase the electrical conductivity. Optimum potential difference is 1.3 volt for this electrolytic process. During electrolysis, pure copper is deposited on the cathode plates and impurities which are soluble and fall to the bottom of the cell as anode mud or ...

LIQUID-LIQUID COPPER EXTRACTION PROCESS

o Feed concentration: Cu MW = 63.54, so 12 g sulfate/L is (CuSO 4. 5H 2 O MW = 249.6) is close to 3 g Cu/L. o The feed solutions should be made up by the TA. o If weakly acidic copper sulfate in water is used as feed, less copper will be extracted from the aqueous phase. Thus the equilibrium will depend on the pH of the aqueous phase.
