By using numerical technique for equilibrium in multicomponent and multiphase systems, a computer model has been developed to simulate the process of nickel flash smelting process. The primary assumption of the model is that six phases in the nickel flash smelting furnace are in chemical equilibrium. The amounts of each component in matte, slag and gaseous phases under equilibrium are calculated by using the data of free energies of formation and activity coefficients of components. Two nickel sulfide species are considered to allow for the modeling of sulfur-deficient mattes. The prediction by the present computer model is compared with the available data. The agreement between the computerprediction and the data is excellent, such that the present computer model can be used to monitor and optimize the actual industrial operations of nickel flash smelting process. The distribution behavior of Ni, Co, Cu, Fe, S, O, C, H, SiO 2, MgO in nickel smelting process is basically dependent on the process factors such as temperature, air flow rate, elemental composition of the charge and oil.
