There are 17 rare earth metals, and their production is a complex multi-stage process. Exports may be in the form of ores or goods at any stage including mined rare earth ores (all containing a tiny mix of rare earths), refined ore concentrates, refined highly pure metals, or products incorporating refined metals (car li-on batteries, magnets or magnet incorporating windmill generators).
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 ...
It is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a "rare-earth element". [8] Yttrium is almost always found in combination with lanthanide elements in rare-earth minerals and is never found in nature as a free element.

Discovered in 1949 in San Bernardino County, California, Mountain Pass mine consists of a bastnäsite ore-body with significant concentrations of rare earth elements. [32] The mine once supplied most of the world's rare earth elements. [33] Mountain Pass is the only operational rare earth mining and processing facility in the United States. [10]
“An Amazon email scam can look exactly like a real Amazon email, or can be poorly crafted, and everything in between,” according to Alex Hamerstone, a director with the security-consulting ...
In the 2003 film The Core, [21] "Unobtainium" is the nickname of a 37-syllable long tungsten-titanium crystal alloy developed by Dr. Edward "Braz" Brazzelton that is able to absorb the extreme pressure and heat of the Earth's molten core and then convert these into usable energy; it's used in building the super resistant outer shell of the ship ...
Ytterbium is found with other rare-earth elements in several rare minerals. It is most often recovered commercially from monazite sand (0.03% ytterbium). The element is also found in euxenite and xenotime. The main mining areas are China, the United States, Brazil, India, Sri Lanka, and Australia.
