Solvent extraction of uranium from leach solutions obtained in processing of Polish low-grade ores.

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 acid (D2EHPA) and tri--butylphosphate (0.

Liquid-liquid extraction of uranium(VI) in the system with a membrane contactor.

Raising role of the nuclear power industry, including governmental plans for the construction of first nuclear power plant in Poland, creates increasing demand for the uranium-based nuclear fuels. The project implemented by Institute of Nuclear Chemistry and Technology concerns the development of effective methods for uranium extraction from low-grade ores and phosphorites for production of yellow cake-UO. The Liqui-Cel Extra-Flow 2.
