China currently dominates the world's supply of rare earths, accounting for approximately 70% of the global mine production and as much as 90% of the refined output.
Rare earth metals are critical to many green energy technologies, including the development of electric vehicles. And for decades, China has played a dominant role in mining, processing and producing them at scale. Beijing has also begun restricting access to them, for trade and diplomatic reasons. The world is now taking note, and looking for alternatives.
The REEs are a group of 17 elements which have similar physiochemical properties. These are the 15 lanthanides from Lanthanum to Lutetium and two other elements, scandium and yttrium. The REEs are classified as heavy rare earth elements (HREEs), light rare earth elements (LREEs) or middle rare-earth elements (MREEs).
