| Abstract: |
| Uranium leaching is achieved by a series of hydrogeochemical interactions between leached uranium solution and uranium minerals. Hydrogeochemistry of uranium leaching have been studied and discussed by scholars at home and abroad. Hydrogeochemical research progress of uranium leaching is system inducted and combed. Oxidation-reduction, dissolve-precipitation, adsorption-desorption of the latest research progress of hydrogeochemical are analyzed. Mechanism of oxidative leaching and all kinds of antioxidants (H2O2, SO2/O2, MnO2, microorganisms, etc.) on oxidation are elaborated. Influence of temperature, hydrochemical properties (Eh, pH, main cation and anion, gas) and gangue minerals on dissolving-precipitation are analyzed. Influence of clay mineral, colloid, organic matter, microorganism on adsorption and desorption are analyzed. Finally, hydrogeochemical research of uranium leaching in future is prospected. |
