Uranium Recovery (Extraction) Methods NRC.gov

Uranium recovery involves one of the following extraction processes. In a conventional uranium mine and mill, uranium ore is extracted from the Earth, typically through deep underground shafts or shallow open pits. The ore is transported to a mill, where it is crushed and undergoes a chemical process to remove the uranium. The uranium is ...

stages of extraction of uranium in the mill process

Uranium mining is the process of extraction of uranium ore from the ground. The worldwide production of uranium in 2015 amounted to 60,496 tonnes . Kazakhstan, Canada, and Australia are the top three producers and together account for 70% of world uranium production.

well-field mechanics for in-situ uranium mining

Conventional mining produces tailings, runoff, and considerable land disturbance—all requiring significant rehabilitation. With in-situ leach mining methods (see diagram at right), disturbance is reduced because only multiple boreholes are drilled for recovery. Rehabilitation is much simpler, consequently the number of in-situ uranium mining ...

Merox - Wikipedia

Conventional Merox for sweetening jet fuel or kerosene. The conventional Merox process for the removal of mercaptans (i.e., sweetening) of jet fuel or kerosene is a one-step process. The mercaptan oxidation reaction takes place in an alkaline environment as the feedstock jet fuel or kerosene, mixed with compressed air, flows through a fixed bed of catalyst in a reactor vessel.

A process for extracting uranium compounds from wet-process phosphoric acid (WPA) includes lowering iron content of WPA to produce a lowered iron WPA, reducing valency of any remaining iron in the lowered iron WPA to produce a reduced iron valency WPA. Uranium compounds are extracted from the reduced iron valency WPA via a solvent extraction process.
