XRD patterns of uranium leaching residue 添加不同氧化剂后浸出尾渣的SEM像如图9所示.由图9可知,添加不同氧化剂后的浸出尾渣形貌具有较大的差异.没有添加任何氧化剂的浸出尾渣以团聚的大颗粒形式存在,说明浸出过程中仅靠浸出液(硫酸)无法破坏其本身的脉石结构,这是导致常规酸浸中浸出时间长,浸出效率低的主要原因.添加氧化剂MnO2和H2O2后,团聚的大颗粒... 浸出尾渣的SEM像 Fig. 9 SEM images of uranium leaching residue 图10 添加不同氧化剂后浸出后尾渣的EDS分析结果 Fig. 10 EDS results of uranium leaching residue 浸出尾渣的EDS分析结果如图10所示.浸出尾渣表面的能谱元素组成基本一致,但添加Fe3+作为氧化......
