Modern methods of recycling spent automotive catalysts and their main disadvantages in industrial practice are considered. The electrochlorination method is proposed as the basis of the platinum-group metals (PGM) recycling technology. As the test of proposed technology a few tons of spent automotive catalysts were processed. The results of the work on the extraction of platinum, palladium, rhodium are analyzed. The extraction rates during experiments were reached for Pt - 97%, Pd - 97% and Rh - 80%.
