Abstract
Vanadium values are recovered from sulphur-containing cokes and ashes derived from heavy oils by a novel process comprising heating in the presence of alkali metal carbonate, contacting the resulting solid residue with water to form a leach and recovering the vanadium values dissolved therein. The heating step solubilizes only alkali metal vanadate and thus the leach solution is substantially free of contaminating substances.
