TREATMENT FOR SPENT PETROLEUM CRACKING CATALYST Abstract of the Disclosure The invention is directed to a process of treating waste materials, particularly petroleum cracking catalyst waste containing contaminating and/or valuable metals to decontaminate the waste and/or recover the metals there- from which process comprises the reduction of the metals contained in the waste in the presence of a slag former such as a silica-alumina composite, a flux such as a Group IA or IIA oxide and a phosphate containing compound. The metals are recovered as metals or metal phosphides in a distinct ferrophos layer. The accumulated metals can be further processed to recover the metal content thereof. The process parallels the electrothermal pro- cess for producing phosphorus which is desirably util- ized as disclosed herein to recover valuable Group VB to Group VIII metals.
