Mineralogical Characteristics of Sulfide in Hongge Vanadium Titano-magnetite
-
摘要: 通过光学显微镜、扫描电镜和电子探针、X射线荧光光谱分析等手段,对四川攀枝花红格矿区钒钛磁铁矿中硫化物的产状与形态、内部结构特征、化学组成及变化等矿物学特征进行了详细研究。结果表明,矿石金属(Co、Ni、Cu、Fe等)硫化物矿物以磁黄铁矿、黄铁矿为主,呈不规则粒状或者呈集合体状分布于钛铁氧化物、硅酸盐矿物粒间,这是硫化物的主要产出形式。从化学成分来看,Co、Ni、Cu与Fe、S含量间的关系并无明显的规律性。硫化物是由磁黄铁矿、黄铁矿和黄铜矿等不同比例组成的矿物体。该研究结果为该矿区钒钛磁铁矿中硫化矿物的选冶工艺以及综合利用提供了重要参考依据。Abstract: In this paper mineralogical characteristics of sulfide in vanadium titano-magnetite of Panzhihua Hongge area,Sichuan province had been extensively investigated by the methods of optical microscope,SEM,EMPA,XRF etc. The observation results reveal that metal (Co,Ni,Cu,Fe,etc) sulfide-based pyrrhotite and pyrite present in the ores and distribute in titanium-ferro oxides and silicate minerals in form of irregular granula or aggregates. The content of Co,Ni,Cu and Fe,S are not significantly related with each other. Sulfide is composed of various contents of pyrrhotite,pyrite and chalcopyrite. The results will help to the comprehensive utilizations of the sulfide in this kind of ore.
