摘　　要：本文以青海某金矿石的原生矿和氧化矿样为研究对象,运用工艺矿物学的研究方法,通过工艺矿物学手段,查明了该矿石中金的赋存状态和分布规律:原矿为花岗型含硫化物金矿床,矿石中的金主要以次显微状(<0.02μm)赋存于毒砂和黄铁矿中,矿石中没有独立的金矿物。毒砂含金量显著高于黄铁矿。氧化矿石的含金量明显高于原生矿。The paper takes the primary ore and oxide ore of some Gold Deposit in Qinghai as the research object,Using detailed processing mineralogy study,through chemical analysis,heavy-sand analysis, microscope appraisal as well as MLA automated analysis.The occurrenceand distribution law of the gold deposit is revealed that the raw ore is granite type gold deposit containing sulfide,gold in the ore is mainly sub-microscopic shape (<0.02μm)hosted in arsenopyrite and pyrite,and there are no independent gold minerals in the ores.Gold contents in arsenopyrite were significantly higher than that of pyrite.The gold content of the ore is higher than that ine the native oxide ore.

关 键 词：金矿 毒砂 黄铁矿 工艺矿物学
