Abstract: (7334 Views)
Carbothermic reduction of Molybdenite in the presence of Magnesium oxide was thermodynamically studied. The stability diagrams for MoS2-MgO and MoS2-MgO-C Systems was prepared. The reduction of MoS2 with Carbon in the presence of Magnesium oxide proceeded through the direct oxidation of MoS2 by MgO to form intermediate molybdenum oxidized Species, MoO2 and MgMoO4. The results showed that the gaseous phase is mainly composed of CO. Stability diagrams for Mo-O-C (Reduction of MoO2 with carbon) and Mo-Mg-C-S-O (Reduction of MgMoO4 with carbon) were also investigated. The results showed that the Reduction of oxidized species leads to the formation of Mo, Mo2C, MoC or MgO products.
