Recycling of Iridium and Ruthenium Waste in Fertilizer Factories

In a typical fertilizer factory, iridium and ruthenium are primarily found in equipment and components used as catalysts. These metals are widely utilized in the production of synthetic ammonia and nitric acid due to their excellent catalytic properties and chemical stability. As equipment ages and wears, components containing iridium and ruthenium become significant sources of waste.Recycling of Iridium and Ruthenium Waste in Fertilizer Factories

In the process of fertilizer production, due to the high value and scarcity of iridium and ruthenium, these wastes usually receive considerable attention. However, due to the complexity and cost of the iridium and ruthenium recycling process, some fertilizer factories fail to fully recover these precious metal components.Recycling of Iridium and Ruthenium Waste in Fertilizer Factories文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47124.html

The recycling process of iridium and ruthenium waste first involves the collection and pretreatment of waste, including sorting, cleaning, and crushing of the waste; then, iridium and ruthenium are extracted from the waste through chemical dissolution and refining steps; finally, the iridium and ruthenium metals are separated and purified through chemical precipitation and purification steps.Recycling of Iridium and Ruthenium Waste in Fertilizer Factories文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47124.html

For example, in recycling iridium and ruthenium from spent catalysts, the catalyst is first physically crushed to increase its contact area with the reaction solution. Then, the crushed waste is placed in an acidic solution to dissolve the iridium and ruthenium elements. In this step, iridium and ruthenium transform into ions in the solution. Subsequently, precipitants are added to convert the iridium and ruthenium ions into precipitates, followed by filtering, washing, and heat treatment to obtain pure iridium and ruthenium metals.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47124.html 文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47124.html
