Extraction of sulfur and vanadium from petroleum coke by ...

Introduction The objective of salt-roasting of refractory metal ores is to render the metal content water-soluble. Salt-roasting converts the metal to an oxidic anion of its maximum valance state. Vanadium in the feed materials is converted on roasting with a source of sodium under oxidizing conditions to soluble sodium salt [1–3].

Vanadium - Wikipedia

Vanadium is a chemical element with the symbol V and atomic number 23. It is a hard, silvery-grey, malleable transition metal.The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) somewhat stabilizes the free metal against further oxidation.. Andrés Manuel del Río discovered compounds of vanadium in 1801 in Mexico by ...
