1. Introduce – Neodymium does not occur in nature in its pure metallic form but coexists with other lanthanide elements within rare earth minerals such as monazite and bastnäsite. – Typically, the extraction and purification of neodymium involve advanced multi-stage saponified solvent extraction (e.g., using P507/P204 systems) and ion-exchange chromatography applied to these raw mineral concentrates to achieve high-purity neodymium oxide (Nd₂O₃). – The resulting high-purity neodymium oxide is a premier strategic material driving modern green technology; when alloyed with iron...
