American Rare Earths Advances U.S. Midstream Strategy with Heavy Rare Earths Study
Event summary
- American Rare Earths has commissioned Tetra Tech to conduct an Oxides to Metals study for its heavy rare earths stream, focusing on samarium, gadolinium, terbium, and dysprosium.
- The study aims to evaluate technologies like molten salt electrolysis and calciothermic reduction to convert heavy rare earth oxides to metals, a critical step before magnet manufacturing.
- The initiative aligns with U.S. policy priorities to reduce reliance on foreign midstream and magnet supply chains, particularly from China.
- The study will provide a process flow diagram, mass balance, major equipment list, and preliminary capital and operating cost estimates.
- American Rare Earths aims to integrate oxide to metal capability with its planned refining operations in Wyoming, enhancing its domestic supply chain.
The big picture
American Rare Earths' study is part of a broader U.S. effort to develop a domestic midstream for rare earth metals, reducing dependence on China. The initiative positions ARR as a key player in securing a U.S.-based supply chain for critical heavy rare earth metals essential for defense and advanced technologies. The strategic move aligns with ARR’s goal of building a secure domestic supply of rare earths, leveraging Wyoming’s mining-friendly jurisdiction and streamlined permitting processes.
