Mardai
Mardai is an abandoned uranium mining town located in the Dornod aimag of Mongolia, in a remote area north of Choibolsan. The Dornod area was prospected for uranium ore by the Soviet Union beginning in the late 1940s. In 1972, a Soviet geological expedition discovered significant uranium reserves and in 1988 the Erdes Mining Enterprise began operation. Mardai was a "secret city" that housed the mine's Russian engineers and technical staff. Mining stopped in 1993 following the fall of the Soviet Union and Mardai, which had housed about 10,000 Soviet personnel, was completely abandoned. Local Mongolian people then scavenged the city for building materials, leaving behind a ruined ghost town.

Uranium Ore
Uranium ore deposits are economically recoverable concentrations of uranium within the Earth's crust. Uranium is one of the more common elements in the Earth's crust, being 40 times more common than silver and 500 times more common than gold. It can be found almost everywhere in rock, soil, rivers, and oceans. The challenge for commercial uranium extraction is to find those areas where the concentrations are adequate to form an economically viable deposit. The primary use for uranium obtained from mining is in fuel for nuclear reactors. Globally, the distribution of uranium ore deposits is widespread on all continents, with the largest deposits found in Australia, Kazakhstan, and Canada. To date, high-grade deposits are only found in the Athabasca Basin region of Canada. Uranium deposits are generally classified based on host rocks, structural setting, and mineralogy of the deposit. The most widely used classification scheme was developed by the International Atomic Energy Agen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
