RECOVERY OF METALS BY INCINERATION OF METAL CONTAINING BASICION EXCHANCE RESIN

摘要

A method of recovering metal values from an ion exchange resin to which a metal species is bound comprising contacting the reaction product stream wit h a basic ion exchange resin such that at least a part of the metal becomes bound to the resin as metal species and incinerating the resin to produce an ash containing the metal and/or oxides of the metal and separating the metal and/or oxides from the remainder of the ash. The method is useful for recovering rhodium catalyst values from homogeneously catalysed hydroformylation reactions of olefins with carbon monoxide.
