| Abstract: |
| ABSTRACT: Through multi-element analysis，XRD，SEM and microscopic analysis and other measurements，the detailed process mineralogical studies on the sedimentary bauxite were carried out to identify the chemical composition，mineral composition，grain size distribution，dissemination and liberation characteristics of the ore. The results showed that mainly metallic minerals are diaspore，hematite and limonite；the mainly nonmetallic minerals are kaolinite，a few quartz and domolite. The results can provide the basic reference for the rational exploitation of the bauxite. |
