Iridium, as a rare and precious metal, plays an indispensable role in modern industry due to its excellent chemical stability and catalytic properties. Especially in the chemical, pharmaceutical and environmental fields, the excellent performance of iridium catalysts makes it a key factor in promoting industrial progress. However, due to the scarcity and high cost of iridium, recycling of spent iridium catalysts has become critical. In this paper, the important application of iridium catalyst will be discussed in depth, and the economic and environmental value of waste iridium catalyst recovery will be revealed in combination with a practical case.

For example, a chemical company based in Hamburg, Germany, uses iridium catalysts to accelerate the production of pharmaceutical intermediates. Over time, the catalyst becomes less efficient and needs to be replaced. The recovery process of waste iridium catalyst is as follows:文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47279.html

Collection and sorting: The waste iridium catalyst is removed from the reactor, sorted and cleaned to ensure that there are no impurities.
Pretreatment: The waste catalyst is treated into powder by grinding and other methods, which is convenient for subsequent treatment.
Leaching and separation: The powder is placed in a specific solvent to leach the iridium component. Iridium is then chemically separated from the other metals.
Purification: Purification of the separated iridium by further chemical reaction.
Reduction and preparation: The purified iridium is reduced into a metal form to prepare a new catalyst.
Recovery of waste iridium catalysts not only reduces the demand for primary resources, but also saves costs for enterprises. It is estimated that the recovery cost of each kilogram of used iridium catalyst is about 5,000 euros, while the price of new iridium catalyst is as high as 15,000 euros/kg. Through recycling, companies both save costs and contribute to environmental protection.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47279.html

However, the process also faces technical and environmental challenges. For example, the effective separation of iridium from other metals and the treatment of harmful substances in waste liquids require professional technology and strict environmental protection measures.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47279.html
With the advancement of science and technology and the enhancement of environmental protection awareness, the recycling technology of waste iridium catalyst will continue to innovate. In the future, this field will develop in a more efficient and environmentally friendly direction, injecting strong impetus into the sustainable development of industry.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47279.html 文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47279.html
