| Abstract Scope |
Rare Earths are critical to the future of green technology, especially for wind turbines and electric vehicle motors. However, reducing these rare earths into the metals is challenging metallurgically and economically. An overview will be given on the state-of-the-art processes for reducing rare earths from the rare earth oxides to the rare earth metal. The benefits and the challenges of the state-of-the art processes will be presented. An overview of novel processes being developed in the field will also be given. These novel processes range from innovations in metallothermic reduction and molten fluoride electrolysis to ionic liquid electrolysis of rare earth oxides and attempts of reducing rare earth oxides using solid oxide membrane electrolysis. This lays the foundation for direction of future trends on commercial rare earth reduction technology. |
