In an integrated process, copper-bearing materials are leached with dilute sulfuric acid and the dilute pregnant leach solution is reacted with ferrous scrap to produce cement copper precipitate containing copper metal, ferrous impurities and normally refractory metal impurities. The raw cement copper ...

copper refining electrolysis. In the electrolysis the impure copper is anodically dissolved and crystallized at the cathode without impurities. The space time yield (currently about 0.03 t/m3) and the specific energy consumption (about 0.4 kWh/kg Cu) represent the main key figures of the process....
