ReElement Scales Up Heavy Rare Earth Oxide Production

ReElement Technologies

U.S. firm ramps up dysprosium and terbium output as global demand for critical magnets rises

Demonstration-Scale Expansion Targets Key Magnet Materials

ReElement Technologies, a U.S.-based subsidiary of American Resources, has significantly scaled up its heavy rare earth oxide production. The company transitioned from lab-scale to demonstration-scale refining, increasing capacity by 50 times. This step enables commercial qualification of magnet-grade dysprosium and terbium oxides, crucial for EV and defense applications.

ReElement processes SEG+ concentrate, which includes samarium, europium, gadolinium, terbium, and dysprosium. The company aims to secure supply for the rapidly growing domestic and allied rare earth markets.

Marion Plant to Begin Commercial Operations This Year

ReElement has begun equipment installation at its commercial-scale rare earth refining facility in Marion, Indiana. Once operational, the site will produce 2,000 t/yr of rare earth oxides and 5,000 t/yr of battery-grade lithium. The first production phase is scheduled for launch by year-end.

Meanwhile, ReElement has already started shipping small weekly volumes of both light and heavy rare earth oxides. These shipments are serving customers across U.S. and allied supply chains, according to the company.

ReElement Expands Globally with African Investment

ReElement is expanding into Africa through a $100mn partnership with South Africa-based Novare Holdings. The firms plan to build critical mineral refining capacity, with site selection expected in the second half of 2025. Additionally, ReElement has deepened ties with a South African supplier to source antimony-bearing ore.

The ore will be processed into antimony sulphide and oxide at ReElement’s facilities in Indiana. Sample refining has already occurred at the company’s Noblesville site, and Marion is set to scale up capacity.

The Metalnomist Commentary

ReElement’s rapid scale-up reflects a strategic U.S. pivot toward secure rare earth sourcing and domestic magnet supply chains. Its investment in antimony and African infrastructure signals a broader ambition to diversify and control critical mineral flows. The move positions ReElement as a rising force in the rare earth and battery metal industries.
