Uranium ore Wikipedia
Uranium is a silverygray metallic weakly radioactive chemical has the chemical symbol U and atomic number 92. The most common isotopes in natural uranium are 238 U ( ) and 235 U ( ). All uranium isotopes present in natural uranium are radioactive and fissionable and 235 U is fissile (will support a neutronmediated chain reaction). Uranium thorium and one radioactive
How is Uranium Produced
Underground mining is necessary where the uranium ore is too far underground to be reached by openpit mining. The uranium ore is blasted and the resulting debris transported to the surface. After both openpit and underground mining the uranium ore concentrated in the extracted rocks is weak usually only around . The rocks are crushed to

The Key Lake mine is a former uranium mine in Saskatchewan is 570 kilometres (350 mi) north of Saskatoon by air on the southern rim of the uraniumrich Athabasca Lake was initially developed to openpit mine two nearby uranium ore deposits the Gaertner deposit and the Deilmann deposit. Mining of this ore ceased in the late 1990s the Key Lake mill now processes uranium
Uranium Mining and Extraction from Ore Stanford University
Uranium Extraction. Uranium leaching is the process by which the uranium is extracted from the raw ore by reacting the material with acid or base. Fig. 2 shows a general process flow for the uranium extraction process. Prior to the leaching process the ore is often given preliminary treatments that can include roasting and grinding.

Natural uranium ( U U) is the basic raw material for nuclear fuel in Pressurized Heavy Water Reactors (PHWR). The energy in the reactor is derived from the fission of U the only fissile isotope in nature. These reactors also transmute the more abundant U to manmade fissile isotope Pu which could be subjected to multiple recycling as fuel in fast reactor for
