Weight change, heat of reaction and oxidizing velocity in roasting of Ni3S2, which is the principal constitution of nickel mattes produced by converting operation, decomposition pressure of NiSO4 and pressure of the mutual reaction between NiSO4 and Ni3S2 were determined. From these results, the roasting mechanism of Ni3S2 was discussed briefly.
