Uranium of uranium tailings pond is the main source polluting the surrounding environment and its long half - life is difficult to be dealt with. In this paper, a uranium tailings pond in southern China is used as an example to analyze the main chemical forms and influencing factors of uranium in seepage using geophysical simulation software PHREEQC. The results show that, （1） Uranium is mainly present in the seepage, accounting for 99. 99% of the total uranium concentration, and the percentage of the six main chemical forms follows UO2F＋ 〉...
