Using a grid of injection and production wells, a mining solution containing an oxidant (sulfuric acid) is circulated through the orebody to dissolve the uranium. The uraniumbearing solution (generally containing less than 0. 1% uranium) is then pumped to a surface processing facility where the uranium is removed using ion exchange resin/polymer.

Uranium Mining. Uranium Milling and Refining. Uranium Hazards and Wastes. The path from raw uranium ore to a form ready for final use in piles, reactors, or the enrichment process flows through many branching steps. The first step, called milling, changed raw ore into uranium concentrate, either black oxide (uranium oxide, U3O8) or soda salt ...

The average concentration of uranium in the earth's crust is about ppm in rocks [ 2 ], less than 1 ppb in surface water, ppb in ground water, and 3 ppb in sea water. About × 10 14 tons of uranium exists in the earth's crust. However, presently, rocks are the only source from which extraction of uranium is viable.

The vast majority of nuclear power reactors use the isotope uranium235 as fuel; however, it only makes up % of the natural uranium mined and must therefore be increased through a process called enrichment. This increases the uranium235 concentration from % to between 3% and 5%, which is the level used in most reactors.

Milling produces a uranium oxide concentrate, which is shipped from the mill. In the milling process, uranium is extracted from the crushed and groundup ore by leaching, in which either a strong acid or a strong alkaline solution is used to dissolve the uranium oxide. The uranium oxide is then precipitated and removed from the solution.

Processing Sites Congress designated 22 inactive uraniumore processing sites for remediation under Title I of UMTRCA in 1978. Many of these sites were abandoned when UMTRCA was passed. Remediation of the 22 sites resulted in the construction of 19 engineered disposal cells that contain uranium mill tailings and associated contaminated material.

recoverable uranium, it is necessary to process from 500 to 5000 kg ore for each kilogram of uranium recovered. To produce the same amount of uranium, therefore, millsize can vary by a factor of 10. Most uranium mills use wet grinding, and the resulting slurry is fed to a leaching circuit where sulphuric acid is added.
