Zn-vapor pretreatment for acid leaching of platinum group metals from automotive catalytic converters

To recover platinum group metals (PGMs) from spent automotive catalytic converters with a smaller environmental load, a Zn-vapor treatment prior to acid leaching was previously proposed. Because PGMs and Zn form alloys which dissolve easily, the pretreatment is believed to reduce the use of both che...
