Abstract
An advanced method and system for processing mixtures containing clay, metals, and pollutants. The process begins with the separation of clay and metal, followed by the detoxification of pollutants using magnetic beads. Enhancement of pollutant treatment is achieved through the application of nano-bubbles generated by a proprietary bubble generator. The method further includes a detailed screening and classification of particles, utilizing magnetic and gravity separation techniques, the latter of which is supported by an innovative anti-leakage net designed to capture and recycle leaked particles. The process concludes with the effective separation and collection of target elements and rare earth elements (REE), employing flotation for the final classification and extraction. This method represents a comprehensive and efficient approach to mixture processing, emphasizing pollutant removal and resource recovery.
