Bayan Obo is a massive production centre among rare earth element facilities. Its operation started in 1957, after its discovery in the 1920s, and it maintains 40% of all global REE reserve quantities. Fifteen distinct types of rare earth minerals emerge from the mine to serve the needs of defence systems, renewable energy, and electronic industries. The enormous dimensions of the Bayan Obo facility position it as the central component for the global distribution of these crucial elements.
More than 48 square kilometres of Inner Mongolia hosts three primary mineral deposits that compose the Main Orebody, with the East and West Orebodies.
