Bor-Öndör

Bor-Öndör is a city in Khentii Province in eastern Mongolia, sitting at an elevation of 1300 meters close to the northern semi-desert edge of the Gobi Desert, with an administrated area of 144 square kilometres. Its population was 6,406 in 2001, 8,510 by 2006 and 8,080 in 2010, which makes it the second most populous city in Khentii Province after Öndörkhaan. Its economy is dominated by fluorspar mining and concentrate production by the Mongolrostsvetmet joint venture, whose plant is the only mineral processing plant of its kind in the country. Soviet geologists surveyed the fluorspar deposits in the 1950s, and in 1973 a Soviet-Mongolian company was created with 49 percent held by the Soviet government and 51 percent by the Mongolian government. The city is on a railway connection to the Trans-Mongolian line, and a paved road connection to Dalanjargalan was completed by 2025. Livestock herding is pressed by the lack of pasture due to mining.
