The shift in the dominance of rare earth supply

Rare earth elements first demonstrated their significant strategic value during World War II. At the Oak Ridge National Laboratory in the United States, cerium fluoride was used as a "flux" to purify rare earths on a large scale through electromagnetic separation for the atomic bomb, marking the first critical applicati…

Why is China's "value machine" for rare earths still difficult for the world to bypass?

China's leadership in the field of rare earths primarily lies in the foundation provided by rare earth resources, followed by complete infrastructure and production (energy) facilities, as well as the ability to provide complete technologies (especially chemical processes).From 2015 to 2022, China became a net importer in terms o…
