Summary of Methods for Recovering Ruthenium from Ruthenium Waste

Recently, I dealt with three different cases of ruthenium waste recycling, each with its unique challenges and requirements, giving me a deeper understanding of the diversity and complexity of ruthenium metal recovery.

The first case involved a batch of ruthenium waste from industrial catalysts. These catalysts contained a large amount of ruthenium, but also mixed with other impurities. To effectively separate the ruthenium metal, I used a method of chemical dissolution and precipitation. First, I mixed the ruthenium catalyst with an acidic solution, dissolving the ruthenium to form a solution. Then, by adding a ruthenium-specific reducing agent, ruthenium was precipitated from the solution. Finally, through filtration and drying steps, I successfully extracted relatively pure ruthenium.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47555.html

The second case was the processing of a batch of discarded ruthenium electroplating waste, which had a lower content of ruthenium. I used an electrochemical purification method. This method is effective in extracting ruthenium from waste material even at low ruthenium concentrations. I first dissolved the waste in an appropriate electrolyte solution, then ruthenium metal was precipitated from the solution during the electrolysis process.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47555.html

The last case was high-purity ruthenium waste from a laboratory. In this situation, the recovery of ruthenium was the most straightforward. I used a simple physical separation method, recovering high-purity ruthenium metal directly from this batch of ruthenium waste through screening and fine processing.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47555.html

Through these three different recycling cases, I realized that choosing the right recovery method for ruthenium waste of various sources and forms is crucial. It is important to consider not only the content and purity of ruthenium but also the physical and chemical properties of the waste.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47555.html 文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47555.html
