| Occurrence and Production of Praseodymium |
 Occurrence
|
| Praseodymium is available in small quantities in Earth's crust (9.5 ppm). It is found in the rare earths minerals monazite and bastnasite, typically comprising about 5% of the lanthanoids contained therein, and can be recovered from bastnasite or monazite by an ion exchange process, or by counter-current solvent extraction. |
