Phase separation behavior between a molten sulfide and molten oxide is investigated in a FeS-FeO-AO ternary system where AO is a strong acidic oxide such as B2O3or P2O5. Experimental results indicate that a wide miscibility gap occurs along the increment of a strong acidic oxide component, The immiscibility behavior based on the experimental results is compared with a previous work on the FeS-FeO-SiO2system to describe the effect of a strongacidicoxide component on the phase separation between molten matte (sulfide) and slag (oxide). Basedupon the regular solution model, ternary immiscibilities for various smelting systems are explained thermodynamically from the binary data.
