An experimental investigation is presented on the oxidation of Fe(II) in aqueous sulphuric acid under oxygen pressure. The effects of partial oxygen pressure, temperature, and initial concentrations of H2SO4 and Cu(II) on the oxidation process rate have been determined within the ranges applied in a new hydrometallurgical process for copper recovery from its sulphide concentrates. The Fe(II) oxidation reaction rate was found to be described by a second-order kinetic equation at a ferrous iron concentration exceeding 3–8 g/l, indicating significant dependence on the parameters examined. This study demonstrates how varying the oxygen pressure can influence the kinetics of this oxidation process and provides a comprehensive analysis of the reaction dynamics essential for improving copper recovery methods.
