Rare earth elements - statistics & facts Rare earths include a list of 17 chemical elements that, over the past decades, have become increasingly sought-after due to their use in many advanced technologies. The end uses of rare earths include the production of magnets, batteries, catalysts, dis...
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
Hedrick INTRODUCTION The rare earth elements (REEs), which include the 15 lanthanide elements (Z = 57 through 71) and yttrium (Z = 39), are so called because most of them were originally isolated in the 18th and 19th centuries as oxides from rare minerals. Because of their reactivity, ...
The growing demand for strategic resources such as rare earth elements (REEs) for development of modern technologies has spurred an increase in mining activities and consequently a release of REEs into the environment, posing a potential threat to human health. Phytoextraction or phytomining, regarded...
The rare earth elements are all metals, and the group is often referred to as the "rare earth metals." These metals have many similar properties, and that often causes them to be found together in geologic deposits. They are also referred to as "rare earth oxides" because many of them ...
