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。
By means of optical microscope, scanning electron microscopy and electron probe, X-ray fluorescence spectroscopy and other means, the occurrence and morphology of sulfides in the vanadium-titanium magnetite in Hongge mining area, Panzhihua, Sichuan Province, the internal structure characteristics, chemical composition and changes of mineralogy Features have been studied in detail. The results show that the sulfide minerals of ore metal (Co, Ni, Cu, Fe, etc.) are mainly pyrrhotite and pyrite, irregularly granular or aggregated in the form of titanium iron oxide, silicate minerals Intergranular, this is the main form of sulfide production. From the chemical composition point of view, Co, Ni, Cu and Fe, S content of the relationship between no obvious regularity. Sulphide is a mineral composed of pyrrhotite, pyrite and chalcopyrite in different proportions. The results of this study provide an important reference for the metallurgical process and comprehensive utilization of sulfide minerals in the vanadium-titanium magnetite in this mining area.
