FIELD: metallurgy.
SUBSTANCE: according to the first version there is used preliminary mixed charge containing components at following ratio, wt %: molybdenum concentrate 69, reducer 31. Thermal treatment is carried out in a graphite can at temperature of combustion 1400-1600°C during 10-15 min. According to the second version there is used preliminary mixed charge containing components at following ratio, wt %: molybdenite concentrate 53-55, reducer 15-17, iron containing compounds 25-27, slag forming components 3-5. Thermal treatment is performed in the graphite can at temperature of combustion 2000-2200°C during 30-40 min.
EFFECT: efficient and ecologically safe thermal process of production of molybdenum and its alloys.
