How palladium is recovered, how palladium carbon is extracted.

In this era, with the rapid development of science and technology, the recycling of precious metals has become a trend. As a rare and widely used metal, palladium has been widely used in electronics, chemical industry and other fields. So how is palladium recycled? How are palladium and carbon extracted? This article will lift the veil of mystery.

First, the recovery of palladium文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-

Palladium is recycled mainly from discarded electronic components, catalysts and chemical waste. During the recycling process, this waste must be sorted and pre-treated to remove impurities and non-metallic parts. Next, palladium is obtained from waste by chemical or physical means.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-

Chemical recovery process
The chemical recovery method uses chemical changes between palladium and certain compounds to extract palladium. In the case of discarded electronic components, palladium is often present in the form of compounds. Palladium is converted into soluble palladium salts by the addition of specific chemicals. The palladium salts are then separated from the solution by precipitation and filtration, and pure palladium is obtained by recovery and electrolysis.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-

Specifically, the common chemical recovery method is to dissolve palladium in the waste with strong acids such as nitric acid and aqua regia to form a palladium salt solution. Oxidants (such as sodium sulfite, sodium bisulfite, etc.) are then added to the solution to restore the palladium ions to metallic palladium. Pure palladium is eventually obtained by filtration, cleaning and drying. In this process, the recovery of palladium can reach more than 90%.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-

Physical recovery method
The law of physical recovery is to use the physical properties of palladium (such as density, melting point, etc.) for recovery. Take spent catalyst as an example. The palladium in these catalysts is usually present in the particles. Palladium particles can be separated from the catalyst by grinding, selection, and other physical methods. Subsequently, the purity of palladium was further improved by re-selection and magnetic separation. Although the physical recovery operation is simple, the recovery rate is relatively low, generally between 70% and 80%.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-

Second, the extraction of palladium carbon文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-

Palladium-carbon is a commonly used catalyst, mainly used in organic synthesis and other fields. Application of palladium carbon, palladium is slowly deactivated as the reaction proceeds. Therefore, the extraction and recovery of palladium carbon has important economic value.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-

Palladium refining consists of the following steps:文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-

Grinding and selection
First, the deactivated palladium-carbon catalyst was treated. Then, different particle sizes of palladium carbon were screened to improve the extraction efficiency.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-

Pickling and oxidation
Next, the palladium carbon is acid-washed with a strong acid (such as nitric acid, hydrochloric acid, etc.). Remove nonmetallic impurities. The palladium in the palladium carbon is then oxidized to palladium salts by heating or adding an oxidizing agent.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-

Recovery and purification
Recovery of a palladium oxide salt solution (e.g. adding an oxidizing agent) to restore palladium ions to metallic palladium. The pure palladium is then obtained by filtering, cleaning and drying. Finally, pure palladium can be refined or made into other forms of palladium products as needed.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-
