摘　　要：利用化学多元素分析、化学物相分析、光学显微镜、扫描电镜等综合手段,研究该金矿的工艺矿物学特征。查明了矿样中金主要以不可见金形式赋存在黄铁矿和毒砂中。由矿石工艺性质可知,只有选择合适的选矿工艺提高综合硫化物的选别指标,才能提高金的选别指标。The features of process mineralogy of the gold ore are investigated by the means of chemical multi-element analysis,chemical phase analysis,optical microscopy,and scanning electron microscopy. The gold in the ore exists mainly in the form of invisible gold occurring in pyrite and arsenopyrite. Under the guidance of the process mineralogy study result,appropriate beneficiation process can be chosen to improve processing indexes for comprehensive recovery of sulfide minerals.
