In connection with the Platinum and Palladium Concentrates produced in the course of processing copper anode slime, utilizing the process of electronically controlled impurity-large chloride dissolving gold, platinum, palladium-ammonium chloride coprecipitating platinum and palladium-SO2 restoring gold-separation platinum and palladium by boiling to refine platinum and palladium. The recovery rate of platinum and palladium is over 98%, the recovery rate of gold reaches to 99%. The process has the advantage of low cost , simple operation, high precious metals recovery.
