Energy Fuels Achieves First U.S. Primary Production of Heavy Rare Earth Terbium Oxide in Decades
Event summary
- Energy Fuels produced its first kilogram of 99.9% pure terbium oxide at its White Mesa Mill in Utah, using U.S.-sourced monazite ore.
- This marks the first U.S. primary production of heavy rare earth terbium oxide in decades, with pilot-scale production meeting global magnet manufacturer specifications.
- The company previously announced production of nearly 30 kg of 99.9% pure dysprosium oxide, another critical heavy rare earth material.
- Terbium and dysprosium oxides are subject to Chinese export controls, highlighting the strategic importance of this U.S. production.
- Energy Fuels plans to expand production capacity, with commercial-scale operations potentially starting in 2027.
The big picture
Energy Fuels' achievement represents a significant step toward reducing U.S. dependence on Chinese-sourced heavy rare earth elements, which are crucial for high-performance magnets used in electric vehicles, defense technologies, and other advanced applications. The company's ability to produce these materials domestically aligns with broader geopolitical efforts to secure critical mineral supply chains. The strategic importance of this development is underscored by the potential to support up to 7 million EVs per year with the planned production capacity.
