In order to enhance the vanadium recovery, the paper introduced the smelting method, batching method of producing FeV65, and casting and finishing. The method smelts FeV65 combining with electric-silicothermic process. It fully uses the chemical reaction heat of V2O5 and Al, depletedly reduces high vanadium slag in three phrase submerged arc furnace to produce qualified FeV65. The vanadium mass fraction of discharged slag is under 0.5%. The smelting recovery is above 95%.
