Uranium ore - Wikipedia

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 ...

Uranium mining by country - Wikipedia

The search for uranium ore intensified during the Cold War. In East Germany an extensive uranium mining industry was established. Uranium was mined from 1947 to 1990 from mines in Saxony and Thuringia by the SDAG Wismut. It was mostly used by the Soviet Union to build nuclear fission weapons, also as fuel for nuclear power plants. In West Germany more limited mining took place at Ellweiler ...

Uraninite - Wikipedia

Uraninite, formerly pitchblende, is a radioactive, uranium-rich mineral and ore with a chemical composition that is largely UO 2, but due to oxidation the mineral typically contains variable proportions of U 3 O 8.Additionally, due to radioactive decay, the ore also contains oxides of lead and trace amounts of helium.It may also contain thorium and rare earth elements.
