摘　　要：在某地浸采铀条件试验现场微酸酸化前后开展2次同源4元素示踪对比试验,通过构建酸化前后不同的溶质迁移模型,量化计算分析酸化对浸出的影响。模拟结果表明:地浸采铀条件试验采场酸化后,粒子有效对流域面积和溶浸范围分别比未酸化地层提高3.5和3.2倍;微酸酸化有利于提高地浸采铀效率。The twice 4 elements tracing contrast tests were conducted before and after micro-acidification at a testing site of in-situ leaching uranium.Through establishment different solute migration models before and after acidification,the influence of acidification on leaching is quantitatively analysed.Simulation results show that after acidification of the well site of in situation leaching of uranium,the effective area of convection and leaching range are increased 3.5 times and 3.2 times respectively compared with the un-acidified tests;micro-acidification is benefit to increase the efficiency of in-situ leaching uranium.
