摘要：
In this paper, we study the character of solute transport in in-situ leaching of uranium in some sandstone uranium deposit in Xinjiang and analyze the effect of convection, molecular diffusion, mechanical dispersion, adsorption, chemical reaction and radioactive decay on migration and distribution of solute in sandstone uranium deposit. The process of in-situ leaching of uranium in sandstone uranium deposit and shrinkage model of leaching core is divided into 3 interfaces, basic equation of solute transport of in-situ leaching of uranium in homogeneous isotropic sandstone uranium deposit is derived, based on law of mass conservation, the hydrodynamic dispersion coefficient and retardation coefficient of solute transport are determined by analysis-optimization method, the calculated values of solution concentration are consistent with the ones of fitting curve of experimental test values by analysis-optimization parameters and the efficiency of our mathematical model is verified through field test of in-situ leaching.
