| Abstract: | The analysis of component mass fraction and distribution of clay minerals in uranium deposit No.512, reveals that most of clay minerals were deposited with the sandstone, partly resulting from the epigenetic alteration. The mass fraction of total clay mineral and smectite can well reflect the changing trend of physical_chemical conditions. The components are similar over all but partly different in sub_interlayered zones in the deposit. Clay minerals can obviously absorb and enrich uranium, but also restrain the uranium enrichment. Finally analysis is made of some unfavourable effects on in_situ leaching techniques resulting from different clay minerals, it is pointed out that more reseach on components of clay minerals should be emphasized in the course of in_situ leaching. |
