What is the use of platinum-iridium strips? What are the ways to extract platinum-iridium strips?

Platinum-iridium strip is an alloy composed of two precious metals, platinum and iridium, which combines the unique properties of both metals, such as extremely high corrosion resistance, good electrical conductivity and excellent chemical stability. This alloy has key applications in many high-precision fields, such as the manufacture of standard resistors, high-temperature thermocouples, and as a key component in a variety of precision instruments.

In order to better understand the value of platinum-iridium strips and the refining process, we take a practical case study. This case took place in 2020 in Los Angeles, USA. A company called Precious Metals Recovery (PMR), which specializes in the recycling and refining of precious metals, has successfully recovered and refined platinum-iridium strips from industrial waste.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47306.html

PMR has recycled used platinum-iridium thermocouples from a factory that makes them. These waste thermocouples have been eliminated because their service life has reached its limit.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47306.html

The first step is preliminary treatment. The used platinum-iridium thermocouples undergo physical treatment, including crushing and sorting, in order to separate the platinum-iridium alloy from other materials.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47306.html

These materials are then placed in specific chemical solvents. In this process, platinum and iridium are dissolved from other materials.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47306.html

Then comes the separation and refining of metals. The dissolved platinum and iridium are separated and extracted through a series of chemical reactions. This includes the use of appropriate chemical reagents to precipitate, extract and purify the two metals.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47306.html

The extracted platinum and iridium are resynthesized into a platinum-iridium alloy in a certain proportion. This step requires precise metering and control to ensure the quality and properties of the alloy.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47306.html

Finally, the prepared platinum-iridium strip is further processed, such as drawing, cutting and polishing, and finally becomes a product that meets the market demand.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47306.html

In this case, PMR recovered and refined about 5 kilograms of platinum-iridium alloy from about 500 kilograms of used platinum-iridium thermocouples. Given the market prices of platinum and iridium at the time and the cost of refining it, the 5kg of platinum and iridium alloy could be worth hundreds of thousands of dollars. Despite the complexity and high cost of the refining process, this business model still has significant economic benefits given the important uses and market demand of platinum-iridium alloys.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47306.html

Through this case, we can not only see the important applications of platinum-iridium strips in industry and technology, but also gain insight into the complexity and challenges of refining platinum-iridium alloys. With the development of science and technology and the continuous progress of resource recovery technology, the method of extracting platinum-iridium strips will become more efficient and environmentally friendly in the future. This is not only conducive to the sustainable use of resources, but also provides a more stable and reliable supply of materials for related industries.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47306.html 文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47306.html
