Ferrovanadium is an iron alloy consisting of vanadium and iron, and is mainly used as an alloy additive in steel making, and high-vanadium ferrovanadium is also used as an additive of a non-ferrous alloy. The common ferrovanadium contains 40%, 60% and 80% vanadium. The main raw material for producing the Chinese ferrovanadium is vanadium-titanium magnetite, vanadium-containing pig iron is smelted by a blast furnace after mineral separation and enrichment, and vanadium slag is extracted in the blowing process of an atomizing furnace or a converter.
