METHOD OF PROCESSING OF TUNGSTEN-CONTAINING ORES

摘要

FIELD: mining and metallurgy industry; processing of ore components of tungsten-containing ores and their concentrates in production of high-purity metal powder; applicable in machine-tool industry in manufacture of cutting tools, in electronic industry in manufacture of tungsten and molybdenum wire. SUBSTANCE: acting on kinetics of decomposition of raw material at early stage of powder production by increasing depth of decomposition, concentration of impurities and power consumption are reduced that is achieved due to introduction of operation of irradiation with gamma quanta in roasting of raw materials. EFFECT: higher efficiency. 2 cl, 2 tbll
