2. Magnetic separation - Wikipedia

   en.wikipedia.org/wiki/Magnetic_separation

   At these mines, a device called a Wetherill's Magnetic Separator (invented by John Price Wetherill, 1844–1906) [4] was used. In this machine, the raw ore, after calcination was fed onto a conveyor belt which passed underneath two pairs of electromagnets under which further belts ran at right angles to the feed belt. The first pair of balls ...

   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.

4. Rare-earth magnet - Wikipedia

   en.wikipedia.org/wiki/Rare-earth_magnet

   Ferrofluid on glass, with a rare-earth magnet underneath. 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.

5. Eddy current separator - Wikipedia

   en.wikipedia.org/wiki/Eddy_current_separator

   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]

6. High-intensity magnetic separator - Wikipedia

   en.wikipedia.org/wiki/High-intensity_magnetic...

   Magnetic separators that used permanent magnets could generate fields of low intensity only. These worked well in removing ferrous tramp but not fine paramagnetic particles. Thus high-intensity magnetic separators that were effective in collecting paramagnetic particles came into existence. These focus on the separation of very fine particles ...

9. Rare-earth element - Wikipedia

   en.wikipedia.org/wiki/Rare-earth_element

   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 ...
