How to recycle used copper and aluminum radiators?

Time: November 12, 2023

With the rapid development of the electronics industry, a large number of copper-aluminized heat sinks that have ended their service life have formed waste resources, which contain valuable copper and aluminum materials. Efficient recycling of copper and aluminum within these radiators is critical for resource conservation and environmental protection. In this regard, we introduce some of the main equipment and technologies that enable efficient recycling of radiators.

Radiator recycling

First, for preliminary crushing, we use a mechanical crusher with adjustable crushing strength. This equipment can break the radiator into block or flake debris with a size of 20-50mm, thereby achieving preliminary separation.

Next, we used magnetic separation technology. Using a magnetic separator with a strong DC magnetic field, we can separate the iron materials in the radiator, leaving only precious copper and aluminum.

The third step is air flow separation. We use the difference in mass density of aluminum and copper to perform fine separation with the help of an air flow separator. Through this method, we can obtain pure copper and aluminum materials, laying the foundation for subsequent recycling.

Finally, we use electrolytic extraction technology. We collect the high-purity aluminum slag and copper slag that have been finely separated in the previous steps and send them into the electrolytic cell. In a high-current electrolysis process, aluminum and copper can be extracted with a purity of up to 99.9% using aluminum and copper as cathodes.
