FIELD: metallurgy.
SUBSTANCE: in method in the capacity of charge it is used vanadium-bearing wastes and lime, herewith in oxidising area it is implemented separation of metal from vanadium-bearing melted slag with periodic or continuous discharge of it from furnace. It is implemented reduction of vanadium oxides from melted slag in reducing zone by introduction into melt of silicon-bearing alloy with acceptable content of aluminium 2-15%, taken in amount for 2-50% more than stoichiometrically necessary for reduction vanadium oxides.
EFFECT: invention provides increasing of vanadium concentration in alloy, reducing of power inputs, improving of ecological situation.
