Process for recoverying valuable metals from waste catalyst |
| abstract |
A method for recovering high purity nickel, cobalt, molybdenum and vanadium from a waste catalyst in high yield by convenient means is provided. The method includes a step of heating a waste catalyst containing valuable metals in a non-oxidizing atmosphere, thereby deoiling an adhered oil content by thermal decomposition, a step of co-milling the deoiled waste catalyst and a chloride to form a chloride of nickel and/or cobalt, a step of water-leaching the co-milled waste catalyst to dissolve nickel and/or cobalt in water, a step of oxidizing leaching residue containing molybdenum and/or vanadium after water leaching to form an oxide or molybdenum and/or vanadium; and a step of subjecting the leaching residue containing the oxide of molybdenum and/or vanadium to alkali leaching to dissolve the molybdenum and/or vanadium in an alkali solution. |
