  • A vision for a transparent global Rare Earth Element

    Rare Earth Elements are fungible. REEs are fungible, meaning that, for example, 1kg of neodymium (Nd) is mutually interchangeable from another 1kg of Nd. In other words you cannot physically differentiate a sustainably sourced REE from a non-sustainably sourced REE without the use of tagging.Rare earths resource distribution and production ,Rare earth elements are collected from uranium mining, which is located in Ontario province. In addition, potential rare earth resources also exist in pyrochlore ores in Quebec province. Some ores containing yttrium and heavy rare earth elements exist in Newfoundland and Labrador provinces. It was reported by Quest Rare Minerals Ltd that they had discovered rich rare earth mineral deposits in

  • Rare-earth element Wikipedia

    A rare-earth element (REE) or rare-earth metal (REM), as defined by IUPAC, is one of a set of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides, as well as scandium and yttrium. Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides and exhibit similar chemical properties. For the same Are Chinese policies disrupting the REE supply chain ,From a resilience perspective, one could assume that China's involvement in developing REE projects abroad is a resilience promoting mechanism as this helps diversification of supply, a core component of a resilient system.

  • Health effects and toxicity mechanisms of rare earth

    An established action mechanism in REE-associated health effects relates to modulating oxidative stress, analogous to the recognized redox mechanisms observed for other transition elements. Adverse outcomes of REE exposures include a number of endpoints, such as growth inhibition, cytogenetic effects, and organ-specific toxicity.

    Recovery of Rare Earth Elements and Yttrium from Rare earth elements and yttrium coal combustion fly ash has been proposed as a way to supplement REE mining. and related mechanism Fractionation of REE, U, and Th in natural ore-forming ,In the US alone, the annual REE consumption currently approaches 20,000 metric tons, and meeting a demand of this scale requires sustainable domestic mining, which, in turn, suggests that either new natural sources of REE (new ore deposits) have to be found, or new technologies must be developed for more efficient extraction of these elements from existing sources. These goals (at least with
