Abstract:
      Feasible processes on non-oxidative treatment of molybdenite roasting was studied by thermodynamic analysis.Molybdenum powder for steelmaking can be obtained by the process of high-temperature vacuum decomposition at the conditions of 1 700~1 900 K and <100 Pa,and gaseous sulfur can be recycled by liquefaction method at 392~490 K.Mo,Mo2C and CaS can be produced over 1 200 K when calcium oxide and carbon are used as desulfurization and reduction agents respectively.Mo,Mo2C and Na2S can be obtained at 900~1 1...
