Production manner of ferromolybdenum from bright water lead ore

摘要

Topic It is low the bright water lead ore of the grade whose copper content is high (Cu: 0.5 - 10wt%) from the manner which produces the ferromolybdenum where copper content is 0.5% or less is offered. SolutionsThis invention further in details, the bright water lead ore and metal aluminum, inserting the iron in the furnace in regard to the production manner of the ferromolybdenum from the bright water lead ore concentrate, produces the ferromolybdenum in lower part by reacting at high temperature, forming the slug where aluminum sulfate and the iron sulfide are the main component on top, most copper which exist in the bright water lead ore (80 - 95%) by the fact that it tries to exist in slug formation, also the te regards the manner where directly copper content produces the ferromolybdenum of 0.5% or less making use of separate copper removal process from the bright water lead ore whose copper content is high. As for this invention, after the former oxidizing, it is possible to make process compact thermite process (Thermite) with in comparison, it possesses the merit which can decrease the consumption of the aluminum which is the reducing agent.
