ABSTRACT:
Vanadium values useful for catalyst regeneration are recovered from compositions/materials comprised thereof, typically spent V.sub.2 O.sub.5 catalysts, by intimately contacting an aqueous suspension of such a material with a gaseous admixture of sulfur dioxide and oxygen, whereby a phase separation thus results, and recovering an aqueous phase constituting a solution of vanadium values.
