American Rare Earths Launches Oxide-to-Metal Pathway Study for Halleck Creek
American Rare Earths has engaged Tetra Tech to conduct an oxide-to-metal conversion study for its Halleck Creek project in Wyoming, targeting heavy rare earths such as samarium, gadolinium, terbium and dysprosium. Deliverables include preferred processing technology, process flow diagrams, equipment lists and preliminary cost estimates.
1. Commissioning Oxide-to-Metal Study
American Rare Earths has commissioned Tetra Tech to assess pathways for converting separated rare earth oxides into metals, marking a key step toward downstream integration of its Halleck Creek project in Wyoming.
2. Focus on Heavy Rare Earths and Technologies
The study will focus on heavy rare earth elements—samarium, gadolinium, terbium and dysprosium—and evaluate processing options including molten salt electrolysis and calciothermic reduction.
3. Study Deliverables and Cost Estimates
Key outputs will comprise a preferred oxide-to-metal processing technology, a detailed process flow diagram with mass balances, a major equipment list, and preliminary capital and operating cost estimates.
4. Strategic Domestic Supply Chain Integration
This initiative supports the company’s goal of creating a secure, mine-to-metal rare earth supply chain in the United States and reduces reliance on foreign midstream processing.
