对张家界杆子坪黑色岩系型镍钼矿进行矿物学分析和扫描电镜研究,发现镍主要赋存于铁-方硫镍矿[(Ni,Fe)S2]、针镍矿(NiS)、方硫镍矿(NiS2)、硫镍矿(NiNi2S4)、辉砷镍矿(NiAsS)、紫硫镍矿(FeNi2S4)、镍黄铁矿[(Fe,Ni)9S8]等;钼主要以“胶硫钼矿”的形式存在。镍钼矿物多与黄铁矿、脉石矿物交代共生,反映出矿物嵌布关系的复杂性。镍钼矿物嵌布粒度不均匀且细小,给选矿带来很大的难度。
The mineralogy and scanning electron microscopy studies of the black rock series nickel molybdenum ore in the Zhangzijian pluton show that the nickel mainly occurs in the [Ni, Fe] S2], nickel (NiS) NiS2, NiNi2S4, NiAsS, FeNi2S4, and [(Fe, Ni) 9S8]; molybdenum is mainly composed of “ Molybdenum mine ”in the form of existence. Nickel and molybdenum minerals and pyrite, gangue minerals account symbiosis, reflecting the complexity of the mineral embedded relationship. Nickel-molybdenum minerals embedded cloth size uneven and small, to the dressing brought great difficulty.
