• Rare-earth elements: recycling or replacement

    The rare-earth elements, or rare earths—the group of 17 chemical elements with atomic numbers 21, 39, and 57 through 71—are not truly rare in terms of their chemical abundance in the Earth’s crust. However, they are typically found in low concentrations in ore and mineral deposits, and the current supply of them is somewhat limited. Notwithstanding their scarcity, demand for them is

  • 10 Rarest Elements on Earth Rarest

    Everyone is probably familiar with the more common elements on the periodic table, such as Hydrogen, Gold, and Oxygen, but the rare elements on this list aren’t talked about often outside of the scientific community. Essentially all of the rarest elements on Earth are radioactive and don’t have commercial/practical uses. Most of these elements are only used for research and don’t even

  • Where are rare earths found Lynas Corporation

    Even our backyards may contain the tiniest amount of rare earths, perhaps a few parts per million. Although the rarest rare earth is nearly 200 times more abundant than gold, these oxidised minerals are considered to be rare because most deposits are of very low quality and concentration, making them uneconomical to mine. The first ever rare earth was discovered by Lieutenant Carl Axel

  • Rare element substitution a tricky proposition News

    A key factor in these advances is new materials containing exotic elements such as niobium and tantalum, and rare earth metals including yttrium and dysprosium. As consumers demand ever better products, the question of the sustainability of these critical elements arises: how urgent is the need to start developing substitute materials or alternative technologies NAS.
