1. Introduce – Praseodymium does not occur in nature in its pure metallic form but is found in rare earth minerals such as monazite and bastnäsite, typically in association with other lanthanides. – The production of praseodymium involves complex separation processes, including ion-exchange and solvent extraction, to refine raw minerals into high-purity praseodymium oxide (Pr₆O₁₁). – The resulting high-purity praseodymium oxide is a vital component in the magnet industry; it is often used as a partial substitute for neodymium in Nd-Fe-B magnets to improve corrosion resistance...
