The dependence on international supplies of rare earth elements (REEs) has prompted the US to explore alternative sources and sustainable technologies for domestic REE production. One potential source is the secondary electronic and industrial wastes across the US. These hazardous wastes require high costs for the maintenance and remediation, while their high-REE contents offer unique opportunities for REE recovery. However, current hydrometallurgical technologies for REE extraction are energy intensive and costly, with low REE recovery efficiency and the generation of hazardous secondary wastes. Thus, it is beneficial to develop environmentally friendly technologies for REE extraction from the secondary wastes. This project aims to develop novel functionalized mesoporous carbon fiber (MCF) and silica materials for effective recovery of REEs from NdFeB magnet scrap.
