    Method for recovering vanadium from magnetite and

    The magnetite concentrate so obtained may comprise as high as 65 iron as Fe 3 O 4 and 0.5 vanadium. This concentrate has been treated by the well-known soda-roast method to recover the vanadium. However the recovered iron is unsuitable as blast furnace feed because of high soda sodium contamination.
