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.
