Ruthenium Recovery: Supercritical Fluid Extraction for Recycling Ruthenium Waste

Supercritical fluid extraction is an innovative technique for recycling ruthenium waste, utilizing the unique physicochemical properties of supercritical fluids to extract metallic ruthenium. In this method, the commonly used supercritical fluid is carbon dioxide, which exhibits both liquid and gas characteristics under specific temperature and pressure conditions. This enables carbon dioxide to penetrate ruthenium waste deeply, effectively dissolving the ruthenium for efficient separation.Ruthenium Recovery: Supercritical Fluid Extraction for Recycling Ruthenium Waste

In the specific process of recycling ruthenium waste, the ruthenium-containing waste is first placed in a specially designed high-pressure reactor. Subsequently, supercritical carbon dioxide is introduced into the reactor under controlled high temperature and pressure conditions, gradually dissolving the ruthenium. This process usually lasts several hours.Ruthenium Recovery: Supercritical Fluid Extraction for Recycling Ruthenium Waste文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47072.html

Next, the ruthenium-containing supercritical fluid is transferred to another low-pressure container. Here, as the temperature drops, the carbon dioxide reverts to a gaseous state, thereby releasing the dissolved ruthenium. This step requires strict temperature control, typically conducted at room temperature, to ensure effective and accurate separation of ruthenium.Ruthenium Recovery: Supercritical Fluid Extraction for Recycling Ruthenium Waste文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47072.html

Supercritical fluid extraction shows significant advantages in ruthenium recovery, but it also faces some challenges. This technology requires relatively expensive equipment and skilled operators. Additionally, research into more types of supercritical fluids is needed to improve the efficiency and selectivity of ruthenium recovery.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47072.html 文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47072.html
