In Situ Leach Mining (ISL) of Uranium

In situ leaching (ISL), solution mining, or in situ recovery (ISR) involves dissolving uranium in the ground and pumping the solution to the surface where the minerals can be recovered. Information from the World Nuclear Association, the global private-sector organization that provides information on nuclear power, nuclear energy, and the role of nuclear in sustainable development.

Uranium Processing

Uranium Processing; Milling. Uranium ore is crushed and processed in uranium mills, located at or near the mines, to extract uranium using chemical processes. A fine powder, called "yellowcake", is the resulting uranium concentrate product and is packed in 55 U.S. gallon ring-sealed drums containing approximately one-half tonne of yellowcake.

Uranium mines and mills

Uranium mines and mills. Uranium is a naturally occurring radioactive element used for fuel in nuclear power reactors. Canada is one of the world''s largest uranium producers. The majority of Canada''s production is exported. Uranium is mined to provide uranium ore which is processed at a milling facility to produce uranium concentrate.

Uranium Ore

Uranium is also produced by solution or in situ mining methods. This process involves circulating weakly alkaline or acid solutions through an ore body continued within a permeable sandstone aquifer. The uranium in the rock is dissolved by the chemicals and the uranium-bearing solution is pumped to the surface from a production well.

Uranium ore

Uranium is a silvery-gray metallic weakly radioactive chemical element has the chemical symbol U and atomic number 92. The most common isotopes in natural uranium are 238 U (99.27%) and 235 U (0.72%). All uranium isotopes present in natural uranium are radioactive and fissionable, and 235 U is fissile (will support a neutron-mediated chain reaction). Uranium, thorium, and potassium are the ...

Potential Human Health Effects of Uranium Mining ...

Uranium mining and processing are associated with a wide range of potential adverse human health risks. Some of these risks arise out of aspects of uranium mining and processing specific to that enterprise, whereas other risks apply to the mining sector generally and still others are linked more broadly to large-scale industrial or construction activities.

Uranium Mining and Fuel

The Mining Process: There are three main methods of mining uranium, or any mineral for that matter. The first is open pit mining, also known as strip mining. It is a cheap mining method and also an extremely environmentally damaging process, as large swaths of earth are stripped away to reveal the mineral deposits.
