Bayan'obo Mining District (Mongolian: ᠪᠠᠶᠠᠨ ᠣᠪᠣᠭ᠋ᠠ ᠠᠭᠤᠷᠬᠠᠢ ᠶᠢᠨ ᠲᠣᠭᠣᠷᠢᠭ, Chinese: 白云鄂博矿区), or Baiyun-Obo or Baiyun'ebo, is a mining district in the west of Inner Mongolia, China. It is under the administration of Baotou City, the downtown of which is more than 120 kilometres (75 mi) to the south.
The mines north of the town are the largest deposits of rare-earth elements yet found and, as of 2005, responsible for 45% of global rare-earth element production.[2][3][4]
In the satellite image at right, vegetation appears red, grassland is light brown, rocks are black, and water surfaces are green. Two circular open-pit mines are visible, as well as a number of tailings ponds and tailings piles.[5]
