“…Under the same experimental conditions, an error of up to 10% will be obtained. In the high-temperature smelting experiment, the volatilization of sulfur in the form of SO 2 or S 2 is inevitable and uncontrollable [19]. Sulfur content affects thermodynamic equilibrium, phase form of products, and separation between slag and metal during smelting.…”

This work discussed the advantages of reducing copper in molten copper slag with low S content. FactSage calculated the distribution of copper at equilibrium under different sulfur contents. The effect of sulfur content on copper recovery under different oxygen partial pressures in 1400 °C was pointed out. The effect of sulfur content on copper recovery in the actual reduction process was explored through experimental research. Under the condition of low sulfur, the recovery ratio of copper and the stability of the experiment have an ideal result in fixed C/O in the experiment.
