Abstract
Accelerated reaction rates and improved yields are accomplished when sulfides of metals of groups Ib, IIb, IVa, Va and VIII of the Periodic Table are oxidized in aqueous medium to convert the sulfide sulfur to elemental sulfur by performing the reaction in the presence of activated carbon.
