Status and progress of fire recovery technology for platinum group metals secondary resources

The recovery of platinum group metals from secondary resources is of great significance for solving the contradiction between the supply and demand and sustainable development of platinum group metals in China. Pyroprocess methods are widely used in industrial production, and they are relatively mature. This paper summarized the research progress of the recovery of platinum group metals by pyrolysis in details. Among these methods, lead, copper, iron, matte and other metal collections are widely applied in industry and more mature technology. The iron and copper collection methods have high recovery rates and promising development prospects. The high temperature chlorination and volatilization method requires expensive equipment and produce toxic gases. The incineration method is only suitable for treating carbon supported catalysts. In the future, it is necessary to conduct in-depth basic research on the related problems in the pyroprocess recovery processes, and at the same time develop new efficient and clean recovery methods to realize the efficient and clean recycling of secondary resources of platinum group metals in China.
