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.
Uranium leaching
situ leaching works by adding acid or alkali plus an oxidizer to groundwater and injecting it into the uranium ore, where it circulates, dissolving the uranium. The solution containing the dissolved uranium is then pumped to the surface for further processing. Both of these mining methods produce a liquid with uranium dissolved in it.

Uranium Facilities | Uatom.org
Only one company: the Eastern Mining and Processing Plant (SkhidGZK) that controls the production sites in Dnipropetrovsk and Kirovohrad regions, three plants and about 20 auxiliary subdivisions in addition to mines has been engaged in uranium ore extraction and production of natural uranium concentrate in Ukraine until recently.
Uranium processing
Uranium meeting nuclear-grade specifications is usually obtained from yellow cake through a tributyl phosphate solvent-extraction process. First, the yellow cake is dissolved in nitric acid to prepare a feed …
Characterization and processing of radioactive uranium
The form of uranium in productive solutions will depend on the concentration of sulfate ions. The main problem of leaching process is the relatively long contact time required to uranium transfer to a solution from phase of sludge. The increase of temperature and acid concentration is one of the ways to intensify the leaching process.
Solvent extraction of uranium from leach solutions obtained …
Solvent extraction of uranium from acidic and alkaline post-leaching liquors that were obtained by leaching of Polish ores is reported in this paper. The stripping of uranium from organic to aqueous phase was also studied. The synergistic mixture of 2-diethylhexylphosphoric ...
Yellowcake
Yellowcake, chemically U3O8, is a uranium concentrate powder recovered from leach solutions. Yellowcake is an intermediate step in processing uranium ores and nuclear fuel production.

Uranium Mining and Extraction from Ore
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 …
Nuclear Fuel Cycle
In the milling process, uranium is extracted from the crushed and ground-up ore by leaching, in which either a strong acid or a strong alkaline solution is used to dissolve …
The nuclear fuel cycle
Although uranium is about 100 times more common than silver, U-235 is relatively rare, at just over 0.7% of natural uranium. The U-235 is separated from uranium ore at uranium mills or from a slurry at in-situ leaching facilities to produce uranium concentrate, which can be used as a fuel. The uranium concentrate is first processed …
