The purpose of uranium mining is to produce fuel for civilian nuclear power plants and for military programs. Extraction of uranium ores, milling and chemical processing to prepare a uranium concentrate, known as yellow cake (U. 3O. 8), are accompanied by the .
Plutonium 239 Nuclear Power
Plutonium 239 239 Pu is a fissile isotope, which means 239 Pu is capable of undergoing fission reaction after absorbing thermal neutron . Moreover, 239 Pu meets also alternative requirement that the amount ( ~ per one fission by thermal neutron) of neutrons produced by fission of 239 Pu is sufficient to sustain a nuclear fission chain reaction.

Cleanup is conducted at all stages of mining and milling. Myth: The transport of uranium concentrates is a dangerous activity. Fact: Uranium that leaves a uranium mill is not a dangerously radioactive substance. Also known as yellowcake, it is not soluble in water and it can easily be recovered in case of a spill.

For mining and milling of uranium a distinction is made between conventional mining and in situ leach (ISL) mining. A conventional mining operation consists of underground/or open pit operation and a process plant to extract the uranium from the host rock. An ISL operation consists of well fields and a process plant to extract the uranium.

Seven uranium mining and milling companies provided data on occupations in three general groups: shaft mine, strip mine, and processing plant. Wyoming has proven reserves of 308 million tons more » of ore or 216,5000 tons of U/sub 3/O/sub 8/ which amounts to about 32% of the proven reserves at a rate of 30 per pound of U/sub 3/O/sub 8/.
URANIUM
First discovered in pitchblende in 1789 by a German chemist, uranium is an element found naturally in rocks, soil, surface water, and groundwater. Because uranium oxidizes quickly in air, it commonly exists as an oxide in ores, such as pitchblende. Natural uranium consists predominantly of three isotopes: 238.
