| 520 | 3 |a“A method has been developed for the preparation of commercial grade vanadium pentoxide from boiler fly ash submitted by Canadian Petrofina Limited. Laboratory tests have shown that a sulphuric acid leach, followed by the oxidation of the leach solution with sodium chlorate and the precipitation of the vanadium with ammonia, will produce commercial vanadium pentoxide of a grade suitable for the production of ferro-vanadium alloys. The overall recovery of vanadium was about 90 per cent and the consumption of chemical reagents was about 3.5 lb H2SO4, 0.25 lb NaC1O3 and 1 lb NH3 per pound of recovered V2O5"--Abstract, p. i. |
