摘要：

Based on the uranium chemical fractions, combined with laboratory experiments and field monitoring data, a prediction model of uranium concentration for in situ leaching pregnant solution was established. It was demonstrated that the kinetics of in situ leaching of uranium is affected by four chemical fractions from exchangeable to oxidizable after the acidification stage, meanwhile the variation of uranium concentration with time displays two trends as high → low and low → high → low, moreover, it is basically consistent with the fourth-ord...
