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.

Jaduguda Mill of UCIL - uraniumcorp.in

Uranium is extracted from ore by hydro-metallurgical process. After three stages of crushing, and two stages of wet grinding, the slurry thus obtained is pumped to leaching pachucas for dissolution of Uranium. The leached slurry is filtered to obtain liquor containing uranium which is purified and concentrated by ion exchange method.
