In Japan, the amount of Mn consumed as an alloying element is similar to that disposed as a steelmaking slag. To recover Mn from steelmaking slag, the separation of P from Mn is necessary. The authors have proposed a novel process by using the sulfurization reaction of slag to make Fe-Mn matte. The equilibrium relation was measured and the empirical model to describe the activity of sulfide in matte was formulated. The kinetic model to simulate the reaction between matte and slag was also constracted. In this model, mass transfer of each cation was described by the double film theory and the equilibrium at interface was assumed. The result of the equilibrium experiment was applied. Although some parameters have to be determined by curve fitting method, the change in every composition of matte and slag can be calculated simultaneously. By this model, the optimum conditions for the operation were simulated.
