| Abstract: | By applying geochemical model PHREEQC,the species of solute transport in process of in-situ leaching and the cause of sedimentation jam in a sandstone type uranium mine,in which the groundwater is high Ca2 ,high SO42-and high salinity,of Xinjiang are studied.Moreover the hydrogeochemical critical value of solute precipitation is studied according to computed saturation index.References and mothods can be provided for solving the problems encountered in in-situ leaching of uranium. |
