| Abstract Scope |
Rare earth elements (REEs) are becoming increasingly important to cater to clean energy applications. Currently, downstream processing like metal fabrication and magnet manufacturing are limited to a few countries. Rising geopolitical tensions and trade supply disruptions can stall technological advancements of nations, and thus addressing these issues is timely. REEs are produced by the reduction of rare earth fluorides and their synthesis involves using toxic chemicals like HF and NH4HF2. In our developed and licensed REMAFS process, ternary Na-Nd-F has been used as a HF-free feedstock for Nd metal production.
The present work investigates the phase formation, thermodynamic stability, melting points, lifecycle & technoeconomic analysis and scalability of water-free Na-RE-F (where, RE=Nd, Nd/Pr and Dy) from RECl3∙6H2O by hydrometallurgical synthesis. The study guided us in identifying suitable feedstock for large scale production of >99.5% pure RE metals to make permanent magnets with (BH)max >40 MGOe). |
