The permanent magnets segment is estimated to witness significant growth during the forecast period. Major rare earth metals used for making permanent magnets are neodymium, praseodymium, dysprosium, gadolinium, terbium, and samarium. These magnets are widely used in military technologies, including precis...
An Analysis of the Environmental Impacts of the Exploitation of Rare Earth Metals WalterLeal Filho, inRare Earths Industry, 2016 1.3Plant Tissues Rare earth elementsare not essential to plants. However, plants can absorb REEs from soil through roots and can uptake REEs via leaves exposed toatmosph...

China is not only specialized in the extraction of rare-earth oxides from the ores, but also in the downstream activities, i.e. the separation into the individual elements, the processing into rare-earth metals, and the production of rare-earth permanent magnets and lamp phosphors. Due to ...
These advances come at a cost, though, as the rare earth elements needed to make them are getting harder to come by. It’s not that rare earth elements like neodymium are all that rare geologically; rather, deposits are unevenly distributed, making it easy for the metals to become pawns ...

Being formed by highly electropositive and electronegative elements, NaCl and KCl, having a stable electron configuration, are not expected to react with transition or rare-earth metals. In the present work we have shown that it is not the case under pressure, as our experiments, originally desi...
Many serious collectors are assembling sets of quarters. Each date becomes an important part to these sets of coins. Numbers minted yearly vary and over time the scarce and rare issues are noticeably difficult to obtain, raising values. Each series is also interesting because of small changes to...
Stock solutions of each rare earth were prepared from the dissolution of the respective salt in distilled water (H2O) to obtain a solution with a concentration of 1000 mg/L and then used on the batch assays: europium (EuCl3.6 H2O; 99.9%) and cerium, (Ce(NO3)3.6 H2O; 99.5%) were purc...
Clay-hosted rare earth element (REE) deposits, generally considered products of extended subtropical weathering of REE-rich igneous protoliths, are a critical source of REEs globally. The Koppamurra deposit of southeast South Australia, in contrast, is developed in Pleistocene lacustrine clays overlying...
