An improved method is described for processing pig iron containing vanadium to obtain a slag containing at least 8 percent vanadium and having a vanadium to iron ratio of at least 0.5 which is directly useful as a refining agent for producing ferrovanadium alloys, the improvement residing in simultaneously introducing a highly oxidizing gas and a protective fluid below the upper surface of a bath of the molten pig iron maintained at a temperature in the range of 2600 DEG to 2900 DEG F. to oxidize vanadium preferentially, as compared to iron, and thereby produce a vanadium-containing slag in which the ratio of vanadium to iron is increased.
