中文摘要: 铀浸出是通过浸铀溶液与铀矿物之间发生一系列水文地球化学作用而得以实现,国内外学者对铀浸出过程中的水文地球化学作用进行了深入研究与探讨。对铀浸出水文地球化学研究进展进行系统归纳和梳理,分析了氧化—还原、溶解—沉淀、吸附—解吸等水文地球化学作用的最新研究进展,重点阐述了氧化浸出的基本原理及各类氧化剂(H2O2、SO2/O2、MnO2、微生物等)对氧化作用的影响,分析了温度、水化学性质(Eh、pH、主要阴阳离子、气体)、脉石矿物等对溶解—沉淀作用的影响,探讨了黏土矿物、胶体、有机质、微生物等吸附剂对吸附作用的影响。最后,对今后铀浸出水文地球化学研究予以展望。
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.
keywords: uranium hydrogeochemistry oxidation-reduction dissolve-precipitation adsorption-desorption
