Which of the following locations are the main source of Rare Earth Elements (REEs) specifically for Lanthanides ?

APakistan, Albania, Finland

BChina, California, Australia

CIndonesia, Algeria, Britain

DGermany, Italy, France

Answer:

B. China, California, Australia

Read Explanation:

  • Rare Earth Elements (REEs), a group of 17 chemically similar elements including the 15 lanthanides (plus scandium and yttrium), are not actually "rare" in terms of crustal abundance. However, they are rarely found in concentrations high enough for economical extraction.

  • China: Currently the world's dominant producer, accounting for the vast majority of global REE mining and processing. Major mines are located in Bayan Obo (Inner Mongolia) and southern provinces like Jiangxi.

  • California (USA): Home to the Mountain Pass mine, which is the only major rare earth mining and processing facility in the United States.

  • Australia: A significant producer, primarily through the Mount Weld mine operated by Lynas Rare Earths. It is one of the world’s highest-grade rare earth deposits.
