摘要
本文对于含有约0.01%铀的高硼炉渣,用核乳胶照相、铀价态化学分析、X射线衍射、电子探针等多种手段,确定了铀在高硼炉渣中的主要存在形式,为选择除铀杂质工艺方案提供了科学依据。
he form of occurrence of uranium in the high boron slag containing 0. 01% uranium was investigated with photoemulsion method, uranium valence chemical analysis, XPD and electronic probe. It was determined: UO2 is the main uranium compound and approximate 4/5 uranium is present submicroscopicly and mainly in the amorphous boron mineral particulates; only less than 1/5 uranium exists microscopically as independent mineral. There are about 60% forsterite and 30% amorphous boron mineral (suanite or asharite) in the slag The results can provide an important basis for rationally selecting process scheme to remove uranium impurity.
