1. Introduce – Samarium does not occur in nature in its pure metallic form but coexists with other rare earth elements within minerals such as monazite, bastnäsite, and samarskite. – Typically, the extraction and purification of samarium involve advanced solvent extraction and multi-stage chemical separation processes applied to these raw minerals to produce high-purity samarium oxide (Sm₂O₃). – The resulting high-purity samarium oxide is a strategic material essential for the permanent magnet and electronics industries; when alloyed with cobalt (SmCo magnets), its unique ele...
