(Reuters) - Rare earth metals are making headlines as demand rises for products from smartphones to wind turbines, and as governments seek secure supply.
The rare-earth elements (REE), also called the rare-earth metals or rare earths, and sometimes the lanthanides or lanthanoids (although scandium and yttrium, which do not belong to this series, are usually included as rare earths), [1] are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals. Compounds containing rare ...
The study authors, however, suggest the value from extracting rare earth metals could be used to offset the costs of improving the way coal ash is stored and managed.
This REY-rich mud has great potential as a rare-earth metal resource because of the enormous amount available and its advantageous mineralogical features," the study reads. The study shows that more than 16 million short tons (15 billion kilograms) of rare-earth elements could be "exploited in the near future." As well as yttrium (Y), which is ...
Rare earths are a group of 17 metals used to make magnets that turn power into motion for electric vehicles, cell phones, missile systems and other electronics. There are no known substitutes.
Has no known biological role, [11] and is extremely rare in the Earth's crust. None known. [11] rhodium: 45: 1: Has no known biological role, [11] and is extremely rare in the Earth's crust. Toxic in some forms. [11] rubidium: 37: 2c: Has no known biological role, although it seems to substitute for potassium, and bioaccumulates in plants.
These minerals contain the 16 rare earth elements which are also known as the lanthanides. [7] [7] The presence of these minerals can be a valuable indicator in geological surveys and mineral resource assessments. [8] [8] There are over 160 rare earth minerals known, but only four of these occur in amounts suitable for mining. [9]
Most rare earth elements are located in China, with the world’s second-largest economy estimated to account for 70% of global rare earth ore extraction and 90% of rare earth ore processing.
