ABSTRACT:
The invention relates to a process of treatment for the recovery of the precious metals, such as platinum, rhodium and palladium, contained in various compositions including a layer of oxide(s) which is deposited on a metal support, in particular worn or spent motor vehicle postcombustion catalysts, in which the layer of oxide(s) containing the precious metals is separated from the metal support by an electrochemical route, the composition to be treated forming one of the electrodes employed or being in direct contact with one of the electrodes employed.
