Abstract
A method for recovery of platinum group metals from a spent catalyst is described. The method includes crushing the spent catalyst to obtain a catalyst particulate material including particles having a predetermined grain size. The method includes subjecting the catalyst particulate material in the reaction zone at a predetermined temperature for a predetermined time period in contact with solid chlorine-containing material and solid silicon-containing material to obtain volatile platinum group metal-containing chloride product, and cooling to convert the product into solid phase platinum group metal-containing materials.
