A wave of investment in rare earth processing infrastructure is reshaping North America's position in the global supply chain. At least five new separation and processing facilities, spanning from Louisiana to Saskatchewan, have been announced or reached major milestones since mid-2025, signaling a structural shift in Western rare earth strategy.
A Continental Build-Out Takes Shape
For decades, the rare earth supply chain has been defined by a single, uncomfortable reality: China controls roughly 90 percent of global rare earth processing and separation capacity. Even when rare earth ore is mined outside China (in Australia, Canada, or the United States) it has almost invariably been shipped to Chinese facilities for the complex chemical separation required to produce individual rare earth oxides.
That paradigm is now under sustained challenge. Driven by a combination of federal defense funding, private capital, and deepening geopolitical anxiety over supply chain concentration, North America has seen a flurry of rare earth separation facility announcements over the past twelve months. At least five major projects have reached construction, commissioning, or significant expansion milestones since mid-2025, collectively representing the most ambitious Western effort to build domestic rare earth processing capacity in a generation.
MP Materials: Vertical Integration from Mine to Magnet
MP Materials, operator of the Mountain Pass mine in California, the only active rare earth mine in the United States, has made the most aggressive move toward full vertical integration. The company's Mountain Pass facility separated approximately 1,300 metric tons of neodymium-praseodymium (NdPr) oxide in 2024 and has begun producing heavy rare earth concentrate through its SEG+ circuit, operational since late 2023.
In August 2025, the U.S. Department of Defense awarded MP Materials a $150 million loan to construct a dedicated heavy rare earth separation facility at Mountain Pass, targeting dysprosium and terbium, elements essential for high-performance permanent magnets used in defense systems, EV motors, and wind turbines. Construction is underway with an expected commissioning date in late 2027.
Meanwhile, MP's Independence Facility in Fort Worth, Texas, which began producing NdPr metal in January 2025, is ramping toward its target of 1,000 metric tons per year of finished neodymium-iron-boron (NdFeB) magnets. The facility represents the first domestic mine-to-magnet capability in the United States. General Motors, Apple, and the DoD have all signed offtake agreements, with Apple committing $500 million in July 2025.
The company has also announced plans for a second, larger magnet plant, dubbed the '10X' facility, with 10,000 metric tons per year of capacity. Backed by a $400 million DoD equity investment and a $1 billion commercial loan arranged by JPMorgan and Goldman Sachs, the plant is expected to be commissioned in 2028. The DoD has guaranteed a 10-year offtake for 100 percent of production at a price floor of $110 per kilogram of NdPr oxide.
Energy Fuels: Monazite Processing at White Mesa
Energy Fuels has carved out a distinctive niche by processing monazite sands, a radioactive heavy mineral byproduct, at its White Mesa Mill in Utah. The facility is the only commercially licensed operation in the United States capable of handling the radionuclides present in monazite, giving it a regulatory moat that few competitors can replicate.
By late 2025, the company had reached commercial-scale rare earth processing, with Phase 1 separation circuits producing individual neodymium and praseodymium oxides. The process simultaneously recovers uranium from the same feedstock, creating a dual-revenue stream that improves project economics. Energy Fuels has positioned White Mesa as a critical link in a non-Chinese rare earth supply chain, bypassing the traditional route of shipping raw material to Asia for processing.
The company is sourcing monazite from heavy mineral sand operations in the southeastern United States and has signed supply agreements with Chemours and other mineral sands producers. Expansion plans call for additional separation circuits to handle heavier rare earth elements by 2027.
Ucore Rare Metals: Louisiana Strategic Metals Complex
Ucore Rare Metals broke ground on its Louisiana Strategic Metals Complex (SMC) at England Airpark in Alexandria, Louisiana, in May 2025. The 80,800-square-foot brownfield facility is designed to separate mid-heavy rare earth oxides, including terbium, dysprosium, and samarium-europium-gadolinium, as well as NdPr oxide, using the company's proprietary RapidSX separation technology.
The project has received $22.4 million in funding from the U.S. Department of Defense through the Army Contracting Command-Orlando, and was granted Defense Priorities and Allocations System (DPAS) status in September 2025, a designation that ensures priority access to materials and services critical to national defense.
Ucore's RapidSX technology, demonstrated at the company's commercial demonstration facility in Kingston, Ontario, since December 2023, claims significantly faster separation kinetics than conventional solvent extraction processes. Early production of heavy rare earth oxides at the Louisiana facility is targeted for the second half of 2026.
Feedstock will initially come from the Tanbreez project in Greenland, operated by Critical Metals Corp, under a letter of intent for 10,000 metric tons per year starting in 2027. The company has also identified its Bokan-Dotson Ridge deposit on Prince of Wales Island in southeast Alaska as a longer-term domestic source.
Vital Metals and the Saskatchewan Cluster
In Saskatoon, Saskatchewan, a cluster of rare earth processing capabilities has emerged that is unique in North America. Vital Metals has been operating its Saskatoon Extraction Facility since September 2022, processing ore from the Nechalacho mine in the Northwest Territories. Nechalacho is Canada's first rare earth mine, and began production in mid-2021.
The $20 million facility uses dense media separation to produce mixed rare earth carbonate at an initial capacity of 1,000 tonnes per year of rare earth oxide (excluding cerium), equivalent to approximately 470 tonnes of NdPr per year. Output is shipped to REEtec in Norway for final separation and purification, and to Ucore in the United States for magnetic rare earth separation, with end customers including Schaeffler Group in Germany for EV traction motors.
Adjacent to Vital Metals' operation, the Saskatchewan Research Council (SRC) has invested $55 million in a rare earth processing facility designed for full vertical integration, from raw processing through separation to finished metals and permanent magnets. The facility represents the first attempt at a complete mine-to-magnet rare earth processing chain in Canada.
Challenges and Uncertainties
Not all projects in the pipeline have advanced smoothly. Lynas Rare Earths, the world's largest rare earth producer outside China, had planned two U.S. separation facilities in Texas: a light REE plant in Hondo and a heavy REE plant in Seadrift, backed by $258 million in DoD contracts. However, in December 2025, CEO Amanda Lacaze indicated the Seadrift project 'might not proceed' after offtake negotiations with the DoD failed, with the company suggesting that the 'America First' policy environment had favored domestically owned competitors like MP Materials.
The episode highlights a tension in Western rare earth strategy: the need for allied supply chain cooperation versus the political imperative to favor domestic companies. It also underscores the financial challenge of building separation capacity from scratch. Rare earth separation is technically complex, capital-intensive, and environmentally demanding, particularly the handling of radioactive thorium and uranium that co-occur with many rare earth ores.
Permitting timelines, feedstock security, and the uncertainty of government funding cycles remain persistent risks. Several of the announced projects depend heavily on DoD contracts and Defense Production Act authorities, which are subject to shifting political priorities.
Strategic Implications
Despite the uncertainties, the breadth of the current build-out is historically unprecedented. The combined planned capacity of the five major North American projects (MP Materials, Energy Fuels, Ucore, Vital Metals/SRC, and the various DoD-backed initiatives) would, if fully realized, represent a meaningful dent in China's processing dominance for the first time in over two decades.
For downstream manufacturers, including automakers, wind turbine producers, and defense contractors, the emergence of non-Chinese separation capacity offers the prospect of supply chain diversification that has been discussed for years but never materialized at scale. The question is no longer whether the West will build rare earth processing infrastructure, but whether it can do so fast enough and at competitive cost to matter in a market still overwhelmingly shaped by Chinese capacity, pricing power, and technological expertise.
The next twelve months will be decisive. Several facilities are targeting commissioning or expansion milestones in late 2026 and 2027. Their success or failure will determine whether the current wave of announcements translates into a durable restructuring of the global rare earth supply chain, or becomes another chapter in the long history of Western rare earth ambitions that failed to achieve commercial scale.
