Description

In this paper, the impact of uranium ore heap leaching on the environment were studied with the case of two long production uranium mines. According to the basic requirements of the radiation environment assessment of the nuclear industry, the surface radon exhalation rate of the mine waste, the concentration of radionuclide of the waste water and the γ radiation level and concentration of radionuclide of the waste were investigated and compared to that of the early conventional hydrometallurgical production of the two uranium mines. The merits and disadvantage of the heap leaching was evaluated, and measures and suggestions were proposed for the improvement of heap leaching techniques. (authors)
