High purity nickel by a simple means from the spent catalyst, cobalt, provides a method for recovering molybdenum, vanadium in high yield. The spent catalyst containing valuable metal is heated in a non-oxidizing atmosphere, deposition and a step of oil removal by thermal decomposition of the oil, spent catalyst and co-ground and chlorides deoiled, nickel and / or cobalt chloride and generating a spent catalyst that co-ground with water leach, oxidize the steps of dissolving nickel and / or cobalt in water, the leaching residue containing molybdenum and / or vanadium after water leaching, molybdenum and generating a / or oxides of vanadium, and alkaline leach leaching residue containing the oxides of molybdenum and / or vanadium, and a step of dissolving the molybdenum and / or vanadium in an alkaline solution, a.
