Researchers at the Guangzhou Institute of Geochemistry, China, developed Electrokinetic Mining (EKM) for eco-friendly extraction of rare earth elements (REEs). EKM uses an electric field to concentrate REEs, simplifying their separation. REEs are 17 metallic elements with critical properties for modern technologies, including magnetic, electronic, and chemical applications. EKM relies on electrokinetics, which involves the movement of particles or fluids under an electric field to extract REEs from ore.
