Rare Earth Elements (REEs) are essential components of modern technology and industry, leading to their increased release into the environment. This review synthesizes current knowledge on the transfer, accumulation, and fractionation of REEs in plants, with a focus on the impacts of REE-triggered stress at different …

The REs are a family of 17 metallic elements formed by the group III (Sc, Y) and the lanthanide series (La–Lu). The name "rare earth" is misleading and does not represent a geological scarcity ( Fig. 1B) ( 71 ). The origin of this description lies in the occurrence of REs as a mixture of elements in minerals, generally at low concentration.

The effects of rare earth (RE) elements on inclusions and impact toughness of a weathering steel (Q355NHBRE) were studied in this paper. The microstructures, inclusions and impact fractures were observed by optical microscopy, scanning electron microscopy and auger electron spectroscopy. The results showed that the addition of RE …

The effects of rare earth (RE) on the microstructure and impact toughness of low alloy Cr-Mo-V bainitic steels have been investigated where the steels have RE content of 0 to 0.048 wt.%. The results indicate that the normalized microstructures of the steels are typical granular bainite (GB) composed primarily of …

The efects of rare earth (RE) elements on inclu-sions and impact toughness of a weathering steel (Q355NH-BRE) were studied in this paper. The microstructures, inclusions and impact fractures were observed by optical microscopy, scanning electron microscopy and auger elec-tron spectroscopy. The results showed that the addition of RE elements ...

The Discrete element method (DEM) is an invaluable tool for studying comminution as it provides detailed information that can help with process analysis as well as trying out new equipment designs before the equipment is physically built. The DEM was used to analyse previous experimental work to gain some insight into the comminution …

Rare earth elements are a group of metals that are critical ingredients for a greener economy, and the location of the reserves for mining are increasingly important and valuable. This infographic features …

In 2021, the world mined 280,000 metric tons of rare earths — roughly 32 times as much as was mined in the mid-1950s. And demand is only going to increase. By 2040, experts estimate, we'll ...

The rapid depletion of high-grade rare earth elements (REE) resources implies that future supplies may be augmented with low-grade ores, tailings, and other unconventional resources to meet cut ...

Thirdly, the very expensive preparation of extremely pure individual rare earth oxides (98--99.999%) is very costly and is reserved for small uses where purity is essential, such as in phosphors and electronic applications. There is a major contrast between the use of mixed or pure rare earth compounds.

The use of rare earth metals (REMs) for new applications in renewable and communication technologies has increased concern about future supply as well as environmental burdens associated with the extraction, use, and disposal (losses) of these metals. Although there are several reports describing and quantifying the production and …
