Rare earth elements can be found in a variety of minerals, but the most abundant rare earth elements are found primarily in bastnaesite and monazite. Bastnaesite typically contains light rare earths and a small amount of the heavies, while monazite also contains mostly the light, but the fraction of the heavy rare earths is two to three times larger.
21/1/2021 Rare earth elements are a group of 17 metals commonly used for their optical and magnetic properties in, for example, lighting, medical radiographs and catalytic converters. To meet the goals of the Paris Agreement, the European Commission has recently highlighted the substantial amounts of neodymium and dysprosium, alongside metals such as graphite and nickel, needed for renewables
The content of the individual rare-earth elements varies considerably from mineral to mineral and from deposit to deposit.
