Zusammenfassung:	It is provided an electrochemical process for recovering platinum group metals (PGMs) from a PGM-containing solid residue, the process comprising the steps of: a) subjecting the solid residue to electroleaching in order to leach the PGMs from the solid residue and, concomitantly, electrodepositing the leached PGMs onto the cathode; wherein electroleaching and electrodepositing are carried out in an electrolyte comprising a deep eutectic solvent (DES) and an aqueous solution comprising chloride ions and having a pH
