摘要：
Compared with traditional uranium mining methods, in-situ leaching uranium mining has the advantages of low cost, environmental protection and less personnel demand, which has been widely used in the uranium mining industry all over the world. Solute transport is a key problem in the study of in-situ leaching of uranium mining. It is of great significance to improve uranium leaching efficiency to understand and master the transport mechanism of in-situ leaching of uranium mining. Firstly, studies on the transport mechanism and transport mode of solute transport of in-situ leaching uranium mining were reviewed in this paper. And the significance of studying solute transport mechanism and transport mode for improving uranium leaching efficiency were summarized. Secondly, the research progress of reactivity solute transport and multi-field coupling model of in-situ leaching uranium mining were emphatically analyzed by researchers at home and abroad in recent years. The complexity of solute transport and the challenges in the research process were described. At last, based on the existing research, it was found that the solute transport of in-situ leaching of uranium mining lacked the research on microcosmic mechanism, gas-liquid-solid three-phase reaction transport and scale conversion, and the coupling model needed to be further improved at this stage. For the above four questions, the article put forward the prospect of recommendations the next step of research direction. © Editorial Office of Chinese Journal of Rare Metals. All right reserved.
