The study on process mineralogy of the Muyuzi iron ore

The characterization of process mineralogy of the Muyuzi Iron ore has been investigated through optical microscope and chemical analysis.The results show the valuable mineral are magnetic and hematite,the primary gangue minerals are hornblende and quartz,and a little Chlorite and augite.The dissemination size of the magnetic is distribution,and dissemination size of the hematite is fine.The relation between magnetic and hematite,quartz,hornblende,pyrite is close,and metasomatic and magnetic is difficult to to be dissociated.The Fe content in hornblende is about 40%,and recovery and utilize of Fe will be influenced seriously.
