+ to Fe3+ by dissolved oxygen caused an increase of redox potential from 520 mV to 580 mV in first 3 d. But in 0.1 mol/L Cu2++0.05 mol/L Fe2++0.05 mol/L Fe3+ solutions, the redox potential decreased from... containing Cu2+. The copper extraction increased with a decrease of the initial redox potential (or the ratio of Fe3+/Fe2+). Key words: chalcopyrite; covellite; chalcocite; leaching; redox potential Cite......
