Abstract: Through multi-element analysis,XRD,SEM and microscopic analysis and other measurements,the detailed process mineralogical studies on the mica mine were carried out to identify the chemical composition,mineral composition,micro morphology,grain composition and dissemination characteristics of the ore.The results showed that mica is mainly dominated by muscovite and biotite,and small amounts of sericite exist in it;gangue minerals are mainly to quartz,garnet,hematite and iepidocrocite.The dissemination relations of mica minerals are complicated and the growth is interbedded,gangue minerals are homogeneously embedded by fine grain and symbiosis with mica,belong to the ore of easy cleavage and difficult separation.The results can provide the basic references for the rational exploitation of the mica mine.
