Tunable Chemistry for Precise Metal Isolation This technology from Los Alamos National Laboratory offers a simpler, faster and more cost-effective way to separate closely related metals—including challenging actinide and lanthanide elements—by replacing complex solvent extraction systems with a flexible, single-step selective precipitation approach. By pairing tailored complexing and precipitating agents, Selective Separation enables precise, tunable separations across a wide range of metal systems while eliminating the need for harsh organic chemicals, reducing waste and lowering operational complexity. This adaptability extends its value beyond nuclear applications to areas such as rare earth element processing, medical isotope production and broader mineral and chemical separations, providing a scalable and environmentally responsible platform for next-generation metal recovery. The Challenge: Separating metals that have nearly identical chemical properties—such as actinides and lanthanides—remains one of the most persistent challenges in nuclear fuel recycling, critical mineral processing and advanced manufacturing. Existing approaches rely on complex, multi-step solvent extraction systems that use large volumes of harsh organic chemicals, require specialized equipment and generate significant secondary waste, making them costly, time-consuming and difficult to scale. These limitations create bottlenecks in recovering valuable materials and complicate efforts to improve e
