MP Materials produced 28,000 tonnes of rare-earth oxide equivalent from Mountain Pass in 2019, and 38,500 tonnes in 2020, or more than 15% of global production. [4] As of late 2020, Shenghe Resources was the sole purchaser of MP Material's rare earth concentrate.
Recycling centres use magnetic separation often to separate components from recycling, isolate metals, and purify ores. [1] Overhead magnets, magnetic pulleys, and the magnetic drums were the methods used in the recycling industry. [1] Magnetic separation is also useful in mining iron as it is attracted to a magnet. [3]
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 ...
FASTRAND was a magnetic drum mass storage system built by Sperry Rand Corporation (later Sperry Univac) for their UNIVAC 1100 series and 418/490/494 series computers. A FASTRAND subsystem consisted of one or two Control Units and up to eight FASTRAND units.
A rare-earth magnet is a strong permanent magnet made from alloys of rare-earth elements. Developed in the 1970s and 1980s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets.
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).

An eddy current separator (ECS) is a machine that uses a powerful magnetic field to separate non-ferrous metals from an input waste or ore stream. The device makes use of eddy currents to effect the separation. Non-ferrous metals typically separated by an ECS include aluminum, copper and die-cast metals. [1]
