摘　　要：通过光学显微镜、扫描电镜、X射线衍射仪、X射线荧光光谱分析等手段,对四川攀枝花红格钒钛磁铁矿选矿产品铁精矿的矿物学特征进行了详细研究。结果表明:铁精矿由Fe、Ti、V、Cr、Cu、Ni、Mn、Ca、Mg、Si、Al、S等元素构成;铁精矿的主要金属矿物有钛磁铁矿,以及少量的钛铁矿、磁黄铁矿和脉石矿物;铁精矿主要矿物的矿物学特征与原矿中主要矿物的矿物学特征相似,都是由主客晶矿物组成的复合矿物。铁精矿的粒度细小且形貌随粒度的减小由粒状向片晶状变化。该研究结果为该矿区铁精矿的选冶工艺以及综合利用提供了重要参考依据。The mineralogical characteristics of iron concentrates in vanadium titano-magnetite of Panzhi- hua Hongge area have been investigated by the methods of optical microscope, SEM, XRD, XRF etc. The measurement and observation reveal that iron concentrates mainly contain Fe, Ti, V, Cr, Si, Mg, Ca, Al, Cu, Ni, Mn, S, and some other elements. The metallic mineral in iron concentrate are major titanium magnetite and a small quantity of ilmenite and pyrrhotite. Mineralogical characteristics of iron concentrates is same as the vanadium-titanium magnetite ores, which are oikocryst and chadacryst crystal compound mineral. Iron ore concentrate has small size, and its morphology changes from granular to lamellae with particle size decreasing.
