| Abstract: | The spent automotive exhaust catalysts are an important secondary resource of platinum group metals. The development history and resource status of automobile exhaust gas purification catalyst were introduced, and some enrichment techniques of recovering platinum group metals from spent automotive exhaust catalysts were reviewed. These technologies include metal capture and chlorination gas phase volatilization method of fire methods, and active component dissolution method, carrier dissolution method, total dissolution method and pressurized high temperature cyanidation method of wet methods. The advantages and disadvantages of these technologies were analyzed. The development direction of optimization process and comprehensive utilization of resources was proposed. |
