The wet method is one of the most common methods for recycling iridium, applicable to various types of iridium waste, including iridium catalysts, iridium-impregnated materials, and discarded iridium compounds. The core of the wet method for iridium recycling involves the chemical dissolution and purification process to extract iridium metal from iridium-containing waste.
The first step in wet method iridium recycling is physical separation and crushing to increase the surface area of the iridium material for subsequent chemical reaction. The iridium waste is then dissolved in an appropriate acidic solvent, transforming the solid iridium into iridium ions in the solution.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47149.html
The subsequent key step is the chemical precipitation of iridium. In this step, hydrogen or methanol is added as a reducing agent to reduce the iridium ions in the solution into iridium metal precipitates. The precipitated iridium metal is then filtered and washed to remove impurities.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47149.html
Finally, iridium purification is required, which includes a series of chemical and electrochemical processes to enhance the purity of the recycled iridium, meeting the needs of industrial applications. Through repeated dissolution, precipitation, and purification steps, high-purity iridium metal is obtained.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47149.html
Compared to other iridium recycling methods like the dry method, the wet method has the advantage of adaptability. It can process various forms of iridium waste and more precisely control chemical reactions, improving the recovery rate and purity of iridium. Future breakthroughs in wet method iridium recycling may include increasing processing efficiency, reducing costs, and minimizing environmental impact. With technological innovation and process optimization, wet method iridium recycling will play a greater role in resource recycling and environmental protection.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47149.html 文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47149.html
