ABSTRACT:
A process is provided for the concentration, separation and/or recovery of precious metals such as platinum and palladium via their soluble amine complexes from solutions by sorbing said complexes in one or more members of a novel class of zeolites. Said novel class of zeolites is characterized by a silica to alumina mole ratio of at least 12 and a constraint index in the approximate range of greater than about 2 to about 12.
