An empirical model has been developed based on optical basicity to calculate the sulfide capacity of metallurgical molten slag. The model estimated sulfide capacities agree well with the experimental data for CaO–MgO–FeO–MnO–TiO2–Al2O3– SiO2–CaF2 multicomponent slags. It is found that the abilities of increasing sulfide capacity in MO–SiO2 (M=Ca, Mg, Fe and Mn) melts follow the order: MnO>FeO>CaO>MgO. Also, substitution of CaO for CaF2 decreases the sulfide capacity and substitution of TiO2 for SiO2 increases the sulfide capacity.
