Catalytic converter platinum recovery process

Catalytic converters are an important part of automotive exhaust systems, in which precious metals such as platinum (PT) have a high recovery value. With the increase of environmental awareness and the increasing shortage of resources, platinum recycling is becoming more and more important. Below, we will introduce the platinum recovery process of catalytic converters in detail.

The first thing to be clear is that the platinum in the catalytic converter is not in the form of a pure metal, but is applied as a catalyst to the ceramic honeycomb structure inside the converter. Therefore, the first step in recovering platinum is to disassemble the catalytic converter and remove the ceramic honeycomb medium.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-

The next step is the grinding and grinding process. In this step, the porcelain honeycomb medium is crushed into small pieces to facilitate subsequent chemical treatment. Through professional crushing equipment, the porcelain medium is broken into pieces of a certain size, and then it is more refined by grinding, increasing the surface area and improving the subsequent extraction efficiency.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-

Then comes the crucial stage of extraction. In this step, we use chemical solvents to extract platinum from ceramic fragments. Generally, strong acid or alkali solution is used to extract it under high temperature and pressure. In this process, the concentration, temperature and extraction time of the solution should be strictly controlled to ensure the efficient extraction of platinum and avoid pollution of the environment.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-

After soaking, the aqueous solution contains platinum ions. Next comes the separation and purification process. The usual methods are electrolysis or chemical precipitation. Platinum ions can be reduced to metallic platinum on the negative electrode by electrolysis. Chemical precipitation is achieved by adding a specific precipitator to convert platinum ions into an insoluble precipitate.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-

The final step is simplicity and ingot casting. After the previous process, we have a relatively pure white gold, but in order to further improve its purity, we must make a concise treatment. Simple white gold can achieve high purity and can even be used to make high-performance scientific instruments or jewelry. Finally, the simple white gold will be cast into ingots that are easy to store and sell.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-

Throughout the recycling process, environmental protection and safety issues are particularly important. The use of strong acids and bases requires strict compliance with operating procedures to avoid harm to operators and the environment. At the same time, the treatment of wastewater and waste residue also needs to meet environmental standards to ensure that it will not cause harm to the ecological environment.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-

The recovery of platinum in catalytic converters is not only economical, but also helpful to the rational utilization of resources and environmental protection. With the advancement of technology and the improvement of environmental awareness, I believe that the platinum recycling industry will become more and more standardized and efficient, contributing to the sustainable development of society.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling- 文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-
