Abstract
A process for recovering and purifying vanadium found in petroleum coke is disclosed. Coke containing V and sulfur is charged to a molten metal bath and dissolved to form a molten metal bath with dissolved carbon, dissolved V metal and dissolved sulfur. At least a majority of the dissolved sulfur is released as H,S by maintaining reducing conditions in the bed, by maintaining a high concentration of dissolved carbon or addition of steam or hydrogen rich hydrocarbon such as methane or some combination of these approaches.
