The process of obtaining ferrovanadium by the electro-aluminothermic process has been studied. This process involves reducing vanadium oxide with aluminum in a slag layer in an electric furnace, using iron additions to achieve a desired alloy composition and lime to flux alumina. The electro-aluminothermic process is more controllable than the aluminothermic process. The chemical composition and viscosity of the slag play a critical role in the smelting results, which can be optimized by adjusting the charge composition and temperature. Is also important to achieve as complete separation of metal and slag as possible. By changing the composition of the charge, the electro-aluminothermic process allows producing ferroalloys ranging from 40 % to 80 % vanadium. An essential advantage of this process is relatively low equipment investment, simple raw material preparation requirements, and high product quality. Waste-free production can be implemented based on this process.
