Ucore Rare Metals Produces High-Purity Pr-Nd Samples Using RapidSX™ Technology in Ontario Facility

Published: Aug 25, 2026 17:41 (GMT+8)
[SMM Rare Earth News] Canadian rare earth refiner Ucore Rare Metals recently announced that its commercial demonstration facility in Kingston, Ontario, has successfully produced high-purity (99.5%) Pr-Nd samples from two different raw material sources. The company used about 2 mt of mixed rare earth oxides from a Vietnamese ion-adsorption clay ore source and about 5 mt of mixed rare earth carbonates from a North American bastnaesite ore source. This achievement validates the versatility of Ucore's patented RapidSX™ rare earth separation technology platform for multiple raw materials with vastly different rare earth element compositions. The technology is chemically identical to conventional solvent extraction but offers faster throughput and a smaller equipment footprint. The company plans to achieve scaled production of Pr-Nd as well as samarium, gadolinium, terbium, dysprosium, and yttrium at the Louisiana Strategic Metals Complex (SMC).

Rare Earth Prices Remain Stable Overall; Post-Holiday Market Trading Awaits Recovery [SMM Rare Earth Daily Review]
[SMM Rare Earth Daily Review: Rare Earth Prices Remain Stable Overall, Post-Holiday Market Trading Awaits Recovery] In the short term, the market will gradually return to its normal pace after the holiday, and price trends depend on the actual fulfillment of orders from downstream magnetic material enterprises. Currently, Pr-Nd prices remain firm and cost support is still in place. If post-holiday orders and restocking demand are gradually released, the price center is expected to stay firm; if downstream acceptance of current price levels is limited, the processing segment's efforts to hold prices firm may face challenges. For medium-heavy rare earths, if terbium-based oxides continue to weaken, attention should be paid to whether the metal side follows with adjustments; dysprosium, gadolinium, holmium, erbium, and other varieties lack independent drivers and are likely to remain stable in the short term.
