Abstract: Using the analyses of chemical composition,mineral constituent,construction and structure,the process mineralogical properties of chambersite deposit in Jixiang county were studied.The result shows that the main useful mineral is chambersite.And the gangue minerals are quartz,dolomite,feldspar,clay mineral and chlorite.The chambersite and the gangue minerals all occurs as aggregate.The aggregate of chambersite is loose,while the aggregate of gangue minerals is compact.So,the process flow of fine crushing-screening can be used to recovering chambersite.Based on the available data,the authors propose that the dissemination characteristics of the mineral aggregate should be taken seriously in the process mineralogical study.
