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 di-agrams 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.
