Abstract： Taking secondary resources of platinum as the research object， a recovery process for platinum of pre-treatment， acidic chloridizing leaching， ammonium chloride precipitation， reduction dissolution， oxidation precipitation and calcination was proposed， which achieved efficient recovery and utilization of platinum. Through single factor conditional experiments， the process parameters were optimized. Under the optimal conditions， the sponge platinum product obtained met the national quality standards， with a direct recovery rate of platinum for 97.19% and a comprehensive recovery rate of platinum for 99%.

Keywords： secondary resources of platinum; recycling; reduction dissolution; sponge platinum
