Claims
- 1. A process for separation of higher metal fractions from lower metal fractions of particulates comprising fluidized catalytic cracking catalyst containing metals from a fluidized catalytic cracking process, comprising classifying classification by elutriation or fluidized centrifugation of said catalyst to split said catalyst into a higher metals-containing fraction and a lower metals-containing fraction and wherein said lower metals-containing fraction is comprised of particulates of larger average diameter than the particulates of the higher metals-containing fraction.
- 2. A process according to claim 1 wherein said metals comprise magnetic metals.
- 3. A process according to claim 1 wherein said classification is accomplished by fluidized cyclone means, screening or vibrating means.
