摘　　要：探讨了三碉金矿床金的赋存状态。通过野外实地调查、实验室分析测试以及室内综合研究,查明了该矿床矿石的矿物组成和化学组成、矿石结构和矿石构造、金矿物粒度大小、矿物形态、矿物成分以及金矿物的嵌布类型。研究表明,矿石中金矿物主要呈角粒状,所占比例为47.50%;以细粒金为主,所占比例为52%,指示三碉金矿金的沉淀方式以交代作用为主;自然金较纯,含Au为94.46%,成色高(946),指示三碉金矿的形成温度较高、深度较深;金主要以游离形式存在,占有率为79.3%~91.2%,矿石细磨能提高金的选别指标。The occurrence of gold in the sandiao gold deposit is discussed. Through the analysis of field investigation, laboratory test and indoor comprehensive study, The mineral composition, chemical composition, ore structure, ore size, mineralogy, mineral composition and the type of gold mineral are identified. The results show that the gold minerals in the ore are mainly in the form of granulite, accounting for 47.50%; the proportion of fine gold is 52%, indicating that the gold deposit of sandiao is mainly metasomatic （94.46%）, indicating that the formation temperature of sandiao gold deposit is higher and the depth is deeper; gold is mainly in the free form, the share is 79.3%- 91.2%, the fine grinding of ore can improve the gold Selection of indicators.
