Abstract Scope |
With the increased emphasis on electric vehicles and wind turbines, the demand for rare earths (RE) – a key component in the high-performance, Dy/Tb-doped Nd2Fe14B magnets used in electric motors and generators – has surged. As US companies look towards manufacturing of these high-performance RE magnets domestically, a steady supply of the necessary REs will be of the upmost importance; and with the primary domestic source of heavy REs (Dy, Tb) being current end-of-life (EOL) magnets, it is imperative that cost-competitive EOL product processing techniques are developed. Since EOL products in addition to target elements contain other materials, the excessive chemical usage due to unwanted leaching of unwanted elements significantly increases operating costs. In this work, we present an acid-free leaching process using Fe salts to selectively extract REs from EOL magnets without expending chemicals on dissolving Fe. This approach shows promise for environmentally friendly and cost-effective RE element recovery. |
