ReElement Produces >99.9% Pure Samarium

ReElement Technologies says it has achieved commercial production of samarium exceeding 99.9% purity using internally developed refining flow sheets. The company reports the result from processing both customer-supplied recycled material and mixed concentrates, highlighting the platform’s multi-mineral, multi-feedstock versatility.

Samarium is a key input for samarium-cobalt (SmCo) permanent magnets, prized for thermal stability and magnetic performance in extreme environments; applications include precision-guided munitions, aircraft actuators, secure communications gear and high-temperature aerospace motors. Producing magnet-grade samarium domestically aims to reduce dependence on concentrated foreign supply chains.

ReElement’s modular refining technology is designed for rapid deployment and co-location with feedstock sources, reducing capital and operational risks relative to conventional solvent extraction and enabling quicker response to customer needs. The expanded Noblesville, Indiana refinery is already capable of producing hundreds of tonnes of ultra-pure rare earth oxides annually.

The platform supports circular supply by processing virgin ore alongside recycled magnets and battery materials. Parent-company financing and a strategic equity facility back feedstock acquisition and capacity expansion. Market observers will monitor commercial offtake and scaling progress through 2026 as demand for defense-grade, high-performance magnet materials grows.
