Metals recovery from spent catalyst |
| abstract |
An improved method for recovering metals from spent catalysts, particularly from spent slurry catalysts, is disclosed. The method and associated processes comprising the method are useful to recover catalyst metals used in the petroleum and chemical processing industries. The method generally involves a pyrometallurgical method and a hydrometallurgical method and includes forming a soda ash calcine of a caustic leach residue of the spent catalyst containing an insoluble Group VIII/Group VIB/Group VB metal compound combined with soda ash, and extracting and recovering soluble Group VIB metal and soluble Group VB metal compounds from the soda ash calcine. |
