Physical Enrichment Steps In The Catalytic Converter Recovery Process
Although fossil fuel vehicles make our lives easier, they emit greenhouse gases into the atmosphere that will create air pollution and climate change. The catalytic converter is an exhaust emission control device that largely prevents these gases released into the atmosphere. It is installed in the exhaust pipe of automobiles. In catalytic converters, platinum group precious metals such as platinum, palladium, and rhodium act as catalysts and each catalytic converter contains approximately 3 to 15 g of platinum group metals.
At the end of their life span catalytic converters are classified as scrap and it is economical and environmentally friendly to recycle this material. The recycling process mainly includes these steps: Firstly the catalytic converter is separated from the metal shell exhaust, this operation can be done with the “Decanning Unit”. This separation stage has automatic blades that can cut the exhausts using hydraulic pressure. While the metal shell remains on the upper layer, the valuable inner part in the form of honeycomb and ceramic powder goes to the next step. Then material goes to a magnetic separator. In this separation process, non-precious metal parts are separated from ceramic by magnetic force. The material that has successfully completed separation and sorting steps is now ready for size reduction in hammer mill and ball mill. In this step it is possible to sell the ceramic powders obtained from the physical process to the refinery companies. Chemical treatment can be continued to produce platinum palladium rhodium with high purity and catalytic converter goes to the leaching and refining unit for chemical recovery.
