摘　　要：为给安徽某铜矿资源合理开发利用提供依据,对其进行了工艺矿物学研究。结果表明:矿石中可回收的主要矿物为黄铜矿、磁黄铁矿、黄铁矿、磁铁矿,伴生金、银可综合回收,脉石矿物主要为石榴石、石英、辉石、滑石等;矿石结构主要有自形—半自形晶粒结构、交代结构、他形晶粒结构,可见填隙结构、星点状结构;矿石构造主要有块状构造、浸染状构造、条纹(条带)状构造、角砾状构造;黄铜矿常呈他形粒状浸染于脉石矿物间隙,部分与黄铁矿、磁黄铁矿、磁铁矿等紧密堆积共生,以中细粒嵌布为主;磁铁矿多呈不规则块状或短条带状集合体形式嵌布,部分沿磁黄铁矿等硫化矿物边缘交代共生;黄铜矿嵌布粒度大小不一,+75μm占8.19%,-13.5μm占25.17%,宜采用阶段磨选工艺回收。In order to reasonably and efficiently develop and utilize a copper ore from Anhui Provence, the research on process mineralogy was investigated. The results show that chalcopyrite, pyrite, pyrrhotite, magnetite are the main valuable minerals, and associated gold and silver can be comprehensively recovered, gangue minerals are mainly garnet, quartz, pyrox- ene, talc, etc.. Mineral structures are mainly idiomorphism-half idiomorphism grain structure, metasomatic texture, anhedral grain, and interstitial structure, stars and pots structure also exists. Mineral textures are mainly massive, disseminated, stripes （band） texture. Chalcopyrite often interstitial in gangue minerals in form of anhedral grain, some closed associated with pyrite, pyrrhotite and magnetite. Chalcopyrite are mainly finely disseminated. Magnetite many disseminated in irregular blocks or short banded aggregates, some intergrowth along the edge of pyrite minerals. The particle size of ehalcopyrite is une- ven,＋75 μm accounted for 8.19% , -13.5 μm accounted for 25.17% , stage grinding stage separation process is proposed.
