以新疆某可地浸矿床砂岩型铀矿不同孔深和孔号的矿芯试样6件为研究对象,采用分步提取的方法对各试样铀的赋存形态进行试验与研究,将铀的赋存形态分为可交换离子态、碳酸盐结合态、有机质结合态、无定型铁锰氧化物/氢氧化物结合态、晶质铁锰氧化物/氢氧化物结合态及残渣态。通过用分步提取法对铀赋存形态进行研究,发现铀的形态分布特征在试样内、试样间、同一矿床的不同层位以及不同的矿床都有明显的差异。因此,对铀的赋存形态研究是非常必要的,同时也可以丰富砂岩型铀矿的成矿机理。

Based on the sample of different hole ore core of sandstone type uranium deposits in Xinjiang,using sequential extraction method to research chemical speciation of uranium of each sample,divided into exchangeable ions,carbonate form,organic form,amorphous Fe-Mn oxide/hydroxide bound,crystalline Fe-Mn oxide/hydroxide bound and residual.Through the study of chemical speciation of uranium,discovered the sample between different layers of the same ore deposits as well as different deposits have significant differences.Therefore,the study of chemical speciation of uranium is necessary,but also enri...
