Mechanism and kinetics of silicothermic reduction of MoS2

1 It can be seen from Fig. 2 (a) that when CaO is added as desulfurizer, the reaction extent is closed to 1 at the reaction time of only 8 min. In the absence of CaO, the reaction extent is below 1 even if the reaction time is prolonged to 30 min. Therefore, CaO as a desulfurizer can greatly promote the silicothermic reduction of MoS 2.

Materials

Generally in the nickel converter slag, metals are mainly in the form of sulfides, which are difficult to separate from slag. Although metal oxides in the slag, such as NiO, CoO, and Cu2O, are easily reduced into metal using carbon, the presence of sulfur inhibits the reduction reaction. In this study, the addition of Fe2O3 to nickel converter slag produced
