METHOD OF FERROMOLYBDENUM PRODUCTION FROM MOLYBDENITE

摘要

FIELD: metallurgy.SUBSTANCE: invention relates to metallurgy and can be used at the production of ferromolybdenum with copper content of 0.5% from low-grade molybdenite with high copper content. According to the method, the following is performed: addition of iron and metallic aluminium to molybdenite with copper content of 0.5-10% and their mixing, reaction of the mixture in the heater at a temperature of 1100-2000°C in a gaseous argon atmosphere and natural cooling of the molten metal at an ambient temperature after the reaction is finished so that ferromolybdenum with copper content of less than 0.5 wt % is obtained.EFFECT: invention allows reducing the consumption of a reducing agent - aluminium - due to direct reduction without any oxidation process by using molybdenite with high copper content.6 cl, 2 dwg, 2 tbl, 6 ex
