Ucore Advances Domestic Rare Earth Processing

Ucore Rare Metals is accelerating deployment of its RapidSX separation technology as part of a U.S.-aligned strategy to reduce reliance on Chinese rare earth exports.

Beijing's April 2025 export controls on seven medium and heavy rare-earths — including samarium, gadolinium, terbium, dysprosium, lutetium, scandium and yttrium — plus related magnets and alloys, have tightened supply for manufacturers and defense suppliers. The most complex stages of the value chain occur post-mining: separation, refining and magnet manufacture, where processing capacity remains heavily China-centric.

RapidSX targets those downstream bottlenecks by offering a flow-sheet aimed at faster, lower-cost separations with smaller environmental footprint compared with conventional solvent-extraction routes. Ucore says its timeline targets early domestic production next year, seeking to establish alternative processing capacity that can serve electric vehicles, renewables, consumer electronics and defense markets.

Analysts note that medium and heavy rare earths are difficult to substitute in high-performance magnets and specialized electronics, so redundant processing capacity is strategically important. The move reflects broader efforts to re-shore critical materials processing and to diversify supply chains amid growing geopolitical tensions over resource controls.
