摘　　要：以新疆某铜镍矿为研究对象,对该矿石的化学组成进行探究,重点关注矿物的嵌布特征,以及铜、镍的存在状态和嵌布粒度等方面展开了深入的研究。结果表明,该矿石主要含有铜和镍两种重要有价元素,铜的品位为0.96%,镍的品位为0.55%。铜主要以黄铜矿的形式存在于矿石中,少量铜分布在蓝辉铜矿和铜蓝矿中,偶尔还可见到一些孔雀石和赤铜矿;而镍则主要存在于镍黄铁矿中,其次是紫硫镍矿。此外,其他金属矿物主要包括褐铁矿,而非金属矿物则主要是以蛇纹石为主(其中部分含有镍)。Taking a copper-nickel deposit in X injiang as the research object,an in-depth study was carried out on the chemical composition of the ore,focusing on the distribution characteristics of minerals,as well as the existing state and particle size of copper and nickel.The results show that the ore mainly contains two important valuable elements:copper and nickel,with a grade of 0.96%for copper and 0.55%for nickel.Copper mainly exists in the form of chalcopyrite,a small amount of copper is distributed in blue chalcopyrite and chalcopyrite,and occasionally some malachite and chalcopyrite can be seen,while nickel mainly exists in nickel pyrite,followed by purple pyrite.In addition,other metallic minerals mainly include limonite,while non-metallic minerals are mainly serpentine(some of which contain nickel).
