FIELD: metallurgy.
SUBSTANCE: method involves distillation of vapours of molybdenum trioxide in vacuum at residual pressure of 1-15 mm Hg and condensation of formed vapours of molybdenum trioxide. Besides, initial tailings are dissolved in molten boron oxide. Distillation of vapours is performed from molten metal at temperature of more than 1350°C, and condensation of vapours is performed at temperature of 800-820°C.
EFFECT: simplifying the technology; improving the quality of trioxide owing to its obtaining in compact state; reducing the cost owing to reducing labour costs and power consumption; improving environmental conditions.
