针对某低品位砂岩型铜矿进行工艺矿物学研究，结果表明，该铜矿石矿物成分复杂，原生硫化铜矿物为黝铜矿、黄铜矿，次生硫化铜矿物为斑铜矿、辉铜矿、蓝铜矿；氧化铜矿物主要为孔雀石；脉石矿物以石英、白云母、高岭土、绢云母为主。原矿含铜0．77％，氧化率为45．45％，为一氧化不彻底的氧化铜矿石。矿石中存在着一部分嵌布粒度较细的铜矿物。由于部分硫化铜矿物常和白云石、黄铁矿共生，部分氧化铜矿物常与褐铁矿互相浸染，因此选择合理的磨矿细度，使细粒嵌布的铜矿物充分单体解离是本矿石获得较好选矿指标的关键。

In this thesis the object of study is a low grade sandstone copper with complex composi -tion.The results of the process mineralogy research showed that the primary sulfide copper minerals are tetrahedrite and chalcopyrite while the secondary sulfide copper minerals are bornite ,chalcocite and azurite .The main oxide copper mineral is malachite and the main gangue mineral is quartz . The grade of copper is 0 .77%and the oxidation rate is 45 .45%in the run of mine .There is a part of copper mineral particles disseminated relatively fine .As the copper minerals often intergrow with dolomite and pyrite and the oxide copper minerals are often blended with limonite ,the key of obtai-ning the good flotation index is a reasonable grinding fineness to ensure full liberation of the fine -disseminated copper mineral particles .
