Abstract:The shortage of platinum resources in China is serious. Platinum is indispensable in chemical industry, petroleum refining, automobile exhaust treatment and other industries. The primary platinum ore reserves are limited, mining is difficult, mining and smelting energy consumption is high, the cost is high, and it is also easy to cause environmental problems such as surface subsidence, vegetation damage, waste residue and wastewater pollution in the mining area. The waste platinum catalyst contains a large amount of platinum metal, and the recovery process can be reused. Economically, the recovery of platinum group metals can reduce the dependence on primary platinum ore, and the cost is low and the enterprise benefit is high; in terms of environment, we should avoid excessive demand for resources and environmental damage, reduce waste emissions, and conform to the concept of resource recycling and environmental protection, which is conducive to China "s sustainable development. This paper introduces the method of recovering platinum from platinum group secondary resources, focusing on the process of leaching and platinum enrichment in solution and the corresponding advantages and disadvantages, as well as the current mainstream recovery methods and prospects for future recovery of platinum.
