A slag-metal equilibrium study was carried out to investigate the effect of rare earth oxides on the sulphur partition between CaO-SiO2 slags and carbon-saturated iron at 1500°C. The sulphur partition was increased with increase in Ce2O3 concentration in the slag. The oxygen potential of the system was found to be controlled by the Fe-FeO equilibrium. Sulphide capacities of CaO-SiO2-Ce2O3 slags measured in the present study agreed well with the values predicted by the optical basicity method. It was tentatively concluded that Ce2O3 decreases the activity coefficient of SiO2 in the CaO-SiO2-Ce2O3 slag.
