Rare earth elementsare not essential to plants. However, plants can absorb REEs from soil through roots and can uptake REEs via leaves exposed toatmospheric particlescontaining REEs, mainly from REE mining areas (Ichihashi et al., 1992; Tyler, 2004; Volokh et al., 1990;Liang et al., 2014)...
elements are scandium and yttrium. Based on quantity, the lanthanides cerium, lanthanum, and neodymium are the most produced rare earth elements.Yttrium, one of the rare earths that was explored first, got its name from the town where it was discovered – Ytterby, Sweden. Rare earth elements ...
Some rare earth elements (REEs) are classified under critical materials, i.e., essential in use and subject to supply risk, due to their increasing demand, monopolistic supply, and environmentally unsustainable and expensive mining practices. To tackle t
Heavy rare earth elements (HREEs) such as Gd–Lu, Sc and Y are irreplaceable metals for a number of critical (including clean) technologies, but they are scarce. Ion-adsorption deposits, which form within weathering crusts, supply more than 95% of the gl
Despite the complexity of rare earth mineral deposits and the fact that their mining operation usually includes very different by-products (such as zirconium, uranium, manganese, niobium, etc.), the evaluation of rare earth elements mining investments does not present much more difficulty than in ...
Rare-earth element - Minerals, Ores, Uses: The content of the individual rare-earth elements varies considerably from mineral to mineral and from deposit to deposit. The minerals and ores are generally classified as “light” or “heavy”; in the former
