Uranium extraction from a low-grade, stockpiled, non-sulfidic ore

In line with the spot-measurements, the cumulative U-export calculations showed, unsurprisingly, that approximately 10% greater U-extraction was achieved with the Fe(III)-rich treatment (Fig. 4, top-right).When compared to XRF measurements which confirmed the unleached ore contained ~ 0.42 g/kg U (Table S2), this corresponded to an averaged final U …

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 leaching process, the ore is often given preliminary treatments that can include roasting and grinding.

Case Study: Uranium Production at Ranger Mine in Australia

Mining operations at Ranger commenced in 1980 with full production starting in October 1981, producing uranium oxide concentrate (U3O8) at a rate of around 3,300 tons per year (World Nuclear Association, 2022). Because the Ranger uranium ore body lies close to the surface, open pit, or open cut, mining is used for access.
