【摘要】 通过光学显微镜观测研究、岩矿石多元素分析、化学物相分析、X射线衍射分析及扫描电镜研究等多种研究手段对本区铁矿石中铜的赋存状态及嵌布嵌镶特征进行研究,查明了铁矿石中的铜在原生铁矿石中以黄铜矿为主要载体矿物,在风化氧化铁矿石中,除黄铜矿占有约45%的铜外,胆矾和无定形铜氧化物的铜占有量达50%以上。黄铜矿的嵌布粒度类型为不均匀中粒嵌布,主要嵌联矿物为磁铁矿、闪锌矿、磁黄铁矿及透辉石、金云母、透闪石、阳起石、蛇纹石等硅酸盐矿物。建议在该地区开展有色金属找矿工作。更多还原

【Abstract】 Through various research methods such as optical microscope observation research, multi-element analysis of rock ores, chemical phase analysis, X-ray diffraction analysis and scanning electron microscope research, the occurrence status and inlay characteristics of copper in iron ore in this area. The study found that copper in iron ore uses chalcopyrite as the main carrier mineral in primary iron ore. In weathered iron oxide ore, in addition to chalcopyrite accounting for about 45% of copper, bile alum and amorphous copper oxide have more than 50% copper. The size of chalcopyrite inlay is uneven medium grain inlay, and the main inlay minerals are magnetite, sphalerite, pyrite and diopside, phlogopite, tremolite, actinolite, snake Silicate minerals such as rhomboids. It is recommended to carry out prospecting for non-ferrous metals in this area.更多还原
