Abstract
The possibility of effective application of a plasma technology to decompose the molybdenum sulphate concentrate, molybdenite, is under consideration. First, the model system MoS2-N2 and then the real concentrate underwent the thermodynamic analysis. It has been shown that in the case of the real system which contains quite a few carbon (∼26 %), initial feedstock decomposes through a stage of refractory molybdenum carbide Mo3C2 formation. The correctness of the thermodynamic calculations has been proven experimentally. It has been demonstrated that 100 per cent decomposition of molybdenum sulphide is reachable under the found experimental conditions. The developed technology enables one to prevent the carry-away of companion rare-earth metals.
