A process for recovery and extraction of the high-purity Pt and Pd from furnace ash and the acid mud was introduced. It consists of leaching by acid,displacement and ion exchange to separate the impure elements. Effective separation of Pt from Pd was achieved by adjusting the valence of Pt and Pd. It was proved that this method is a simple and practical process.
