~250,250~150,150~74,74~55以及小于55 μm的6个不同粒径的样品,铀尾矿的粒径分布率及铀含量分析结果如表2所列. 表1 铀尾矿的 ICP分析结果 Table 1 ICP results of uranium tailings 表2 铀尾矿粒径筛分实验结果 Table 2 Results on particle size distribution of uranium tailings 由表2可知,铀尾矿的粒径分布基本均匀,但总体颗粒粒径偏大,其中粒径大于150 μm的颗粒占总量的75%以上,这主要是由原矿堆浸过程中颗粒尺寸所决定的.从各粒径范围内铀含量的分析结果可知,铀含量在不同粒径下的分布差别较大,其中55 μm以下的小粒径中铀含量最高,达到0.014%,已超过铀尾矿的平均铀含量0.008%,随着颗粒粒径的增大......
