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
