Where are rare earth elements most often mined?

Rare earth elements are not actually all rare, but they are usually dispersed and difficult to mine and separate. China has long been the dominant producer, especially from the Bayan Obo region in Inner Mongolia, which is one of the world’s best-known rare earth mining areas. Other important sources include Australia’s Mount Weld deposit and the Mountain Pass mine in the United States. These elements are essential for magnets, batteries, wind turbines, and electronics. Their production matters because modern technology depends heavily on a secure supply chain.
