摘　　要：深入探讨铀溶解、迁移以及沉淀成矿特征对于研究铀基本性状、铀矿成因、铀水冶和污染治理都至关重要。多年来的实践研究证明,热力学计算和与之有关的铀溶解实验得出的相图具有科学性和实用性,从中可以获得关于成矿作用中铀迁移形式、沉淀的物理化学条件以及成矿机制的认识。通过梳理近年来发表的铀溶解与矿物平衡的Eh-pH图、各类新相图图解及其应用现状,并结合相关图解的物理化学含义提出了若干认识。The characteristics of uranium dissolution,migration and precipitation is crucial to understand and study the basic properties of uranium,uranium ore formation,uranium hydrometallurgy and pollution abatement.Over the years,numerous experimental studies have proven that the thermodynamic calculations and the phase diagrams were scientific and practical,and thus the physical and chemical conditions of uranium precipitation,the form of uranium migration and the metallogenic mechanism were obtained.Recently,some new insights have been provided into the physical and chemical implication of the Eh-pH diagram which is related to uranium dissolution and the mineral balance as well as many other newly published phase diagrams.In addition,some problems were also pointed out that other researchers have neglected in the application research.
