摘　　要：为了探索内蒙某铁矿石的工艺矿物学性质,对该矿石开展了较为全面的工艺矿物研究,结果表明:该矿石全铁品位为23.52%,矿石中的铁主要以磁性铁的形式存在,占总铁的85.60%,其次是赤铁矿、褐铁矿中的铁,占总铁的7.35%,以硅酸盐形式存在的铁占总铁的6.33%,只有微量的铁在硫化矿物中,占总铁的0.72%;矿石的主要金属矿物为磁铁矿,含有少量的赤铁矿、黄铁矿,可见微量的黄铜矿和闪锌矿,脉石矿物主要有石英、长石(钾长石、钠长石、斜长石)、角闪石(阳起石、绿钠闪石等)、云母(黑云母、白云母等)、绿泥石、方解石、磷灰石等;通过对该矿石开展系统的工艺矿物学研究,为该类资源的综合开发利用提供了主要的基础数据支撑。In order to explore the technological mineralogical properties of an iron ore in Inner Mongolia,a more comprehensive technological mineral study was carried out on the ore.The results showed that the iron grade of the ore was 23.52%,and the iron in the ore mainly existed in the form of magnetic iron.85.60%of the total iron,followed by iron in hematite and limonite,accounting for 7.35%of the total iron,iron in the form of silicate accounting for 6.33%of the total iron,only a trace amount of iron in sulfide minerals,it accounts for 0.72%of the total iron;the main metal mineral of the ore is magnetite,which contains a small amount of hematite and pyrite,and traces of chalcopyrite and sphalerite are visible.Gangue minerals mainly include quartz and feldspar(potassium Feldspar,albite,plagioclase),hornblende(actinolite,chlorite,etc.),mica(biotite,muscovite,etc.),chlorite,calcite,apatite,etc.The ore carries out systematic technological mineralogical research,which provides major basic data support for the comprehensive development and utilization of this type of resource.
