A critical review on solvent extraction of rare earths
Different rare earths are needed to supply the required functionality in these applications. In some cases, a single rare earth element may be required, such as La for nickel-metal hydride batteries, but other applications require a mixture of rare earths, for example Nd and Pr for rare earth magnets and Eu (or Tb) and Y for rare earth phosphors.
California rare earths miner races to refine amid US-China
After processing, rare earths need to be turned into rare earth magnets, found in precision-guided missiles, smart bombs and military jets. But China controls the rare earths magnet industry, too. Litinsky and peers are betting that by bringing rare earths refining back to the United States, it will encourage other investors to build magnets and other related parts in the country as well.
Especially needed a The role of the rare earth metals in the developed economies is heavy rare earth elements (HREE). The main consumers of rare earth elements are China, Japan, US, EU. The main suppliers of rare earth elements in the United States in 2000-2005 they were China, France, Japan and
