Abstract
The oxidation potential, given as the base-ten logarithm of the oxygen partial pressure in bars and the temperature [log pO2/T, °C], defines the state of oxidation of pyrometallurgical extraction and refining processes. This property varies from copper making, [−6/1150]; to lead/zinc smelting, [−10/1200]; to iron smelting, [−13/1600]. The current article extends the analysis to the smelting of copper and nickel/copper sulfide concentrates to produce mattes of the type Cu(Ni)FeS(O) and iron silicate slags, FeOxSiO2—with oxidation potentials of [−7.5/1250].
