Uranium in Poland: Resources and Recovery from Low

The presented studies deal with an assessment of the possibility of uranium recovery from the low-grade uranium resources in Poland. Uranium was leached from the ground uranium ores with efficiencies in 81–100% range that depend on the type of ore and leaching solution used. In the next step, the post-leaching solution was treated by the solvent extraction or ion exchange chromatography to ...

Uranium is recovered from refractory carbonaceous sulfide ores or concentrates by leaching with nitric acid, followed by sorption on an ion exchange resin. In addition, the nitric acid leach solution is regenerated and recycled. Thus, 94 pct of the u in an ore containing u 0.50, Organic carbon 8.91, and s 6.3 pct was leached with 3.0M hno3 at 120 deg c.

2017-11-29  A new process for extracting uranium from ores with carbonate solutions is described. Leaching is carried out under oxygen pressure to ensure that all the uranium is converted to the soluble hexavalent state. By this method, alkaline leaching can be used successfully to treat a greater variety of ores, including pitchblende ores, than has been possible in the past. The advantages of carbonate ...

Uranium gives 500 XP when mined, however, after uranium decay (which happens right after the ore is mined), the player will only have gained 150 per bit mined. For example, if the player mined 1 bit of uranium, their uranium mass is 500 (XP). The player will then lose 350 XP over time ...
