METALLURGY OF COPPER-EXTRACTION OF COPPER .

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 sludge.

The hydrometallurgical technique involving crushing, leaching, solvent extraction (SX), and electrowinning is being applied to recover copper from these low-grade copper resources [3,4]. SX is one key unit operation in the hydrometallurgical process because it determines the copper separation from the leaching solutions and also has great influence on the following electrowinning efficiency [ 5 ].

Solvometallurgical process for extraction of copper from .

Extraction of copper from sufidic ores, either by pyrometallurgy or hydrometallurgy, has various limitations. In this study, a solvometallurgical process for the extraction of copper from sulfidic ore minerals (chalcopyrite, bornite, chalcocite and digenite) was developed by using an organic lixiviant (FeCl 3 as oxidizing agent and ethylene glycol (EG) as organic solvent).
