  2. Rare-earth mineral - Wikipedia

    en.wikipedia.org/wiki/Rare-earth_mineral

    Many rare-earth minerals include rare-earth elements which thus hold the same significant purpose of rare-earth minerals. [5] Earth's rare minerals have a wide range of purposes, including defense technologies and day-to-day uses. [6] This would be associated with alkaline magmas or with carbonatite intrusives. Perovskite mineral phases are ...

  3. Rare-earth element - Wikipedia

    en.wikipedia.org/wiki/Rare-earth_element

    The rare-earth elements (REE), also called the rare-earth metals or rare earths, and sometimes the lanthanides or lanthanoids (although scandium and yttrium, which do not belong to this series, are usually included as rare earths), [1] are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals. Compounds containing rare ...

  4. Neodymium - Wikipedia

    en.wikipedia.org/wiki/Neodymium

    Neodymium is typically 10–18% of the rare-earth content of commercial deposits of the light rare-earth-element minerals bastnäsite and monazite. [14] With neodymium compounds being the most strongly colored for the trivalent lanthanides, it can occasionally dominate the coloration of rare-earth minerals when competing chromophores are absent.

    Scientists say Florida phosphates are significant sources of rare earth elements, highly sought for everything from cell phones to EVs.

  8. Yttrium - Wikipedia

    en.wikipedia.org/wiki/Yttrium

    Yttrium is almost always found in combination with lanthanide elements in rare-earth minerals and is never found in nature as a free element. 89 Y is the only stable isotope and the only isotope found in the Earth's crust. The most important present-day use of yttrium is as a component of phosphors, especially those used in LEDs.

  9. Praseodymium - Wikipedia

    en.wikipedia.org/wiki/Praseodymium

    Praseodymium is not particularly rare, despite it being in the rare-earth metals, making up 9.2 mg/kg of the Earth's crust. [43] Praseodymium's classification as a rare-earth metal comes from its rarity relative to "common earths" such as lime and magnesia, the few known minerals containing it for which extraction is commercially viable, as ...
