In the world of precious metals, ruthenium and iridium are known for their unique properties and wide range of applications. Although the two metals are adjacent to each other in the periodic table, they are distinct in their chemical properties, applications, and market value. By exploring their differences, and a real recycling case, we can gain a deeper understanding of the importance of these two rare metals.
The value and application of ruthenium and iridium
Ruthenium, atomic number 44, is a hard, brittle, silvery-white metal. It is mainly used in electronic equipment, cemented carbide, chemical catalysts and jewelry manufacturing. Ruthenium's corrosion resistance and conductivity make it extremely important in the manufacture of heat-resistant devices and electronic contacts.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47442.html
Iridium, atomic number 77, is a very hard and dense metal with significant corrosion resistance. Iridium is mainly used in the manufacture of high-temperature materials, electronic devices, automotive spark plugs, and as a reinforcement material for platinum alloys.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47442.html
Difference between ruthenium and iridium
Although ruthenium and iridium are both platinum group metals, there are clear differences in their chemical properties and applications. Ruthenium is relatively lighter and has higher hardness, which is suitable for applications requiring wear resistance and high strength. Iridium is used in applications in extreme environments due to its unique resistance to high temperatures and corrosion. In addition, iridium is generally more expensive than ruthenium in terms of market value, reflecting differences in their rarity and difficulty in production.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47442.html

Procedure:
Collection of waste materials: Parts containing ruthenium and iridium are collected from waste electronic equipment.
Pretreatment: These parts are disassembled to separate the parts containing precious metals from other materials.
Chemical extraction: Extraction of substances containing ruthenium and iridium by chemical leaching and electrochemical treatment.
Refining and separation: The extract goes through a multi-step refining process to separate pure ruthenium and iridium.
Finished product preparation: The conversion of pure metal into a form for industrial or commercial use.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47442.html
Price: A total of about 20 kilograms of ruthenium and iridium were recovered from the waste electronics. At market prices at the time, ruthenium was estimated to be worth about $30 per gram and iridium about $520 per gram, with a total recovery value of several million dollars.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47442.html
Through this case, we can not only see the high value of ruthenium and iridium as precious metals, but also understand the importance of their recycling for resource reuse and environmental protection. Efficient recycling not only reduces the need to extract these rare resources, but also provides a sustainable way to recycle them.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47442.html 文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47442.html
