通过显微镜及能谱分析手段对青海某金银多金属矿石中金、银的赋存状态进行详细的研究。结果表明，矿石中金矿物主要为银金矿，全为显微金，嵌布状态以硫化物包裹金为主，粒间金较少；银矿物以银金矿、辉银矿为主，其次部分以类质同象形式赋存于银黝铜矿中，主要载金、银矿物有黄铁矿、毒砂、方铅矿、白铅矿等。对金、银赋存状态的研究为选矿工艺设计提供了依据。

The occurrence of gold and silver in a polymetallic deposit in Qinghai is detailedly studied with the help of mineralogical microscope and Energy Dispersive.The results show that the contained gold minerals are mostly electrums,taking the form of gold inclusion by sulfide and the rest taking the form of intergranular gold.Similarly the contained silver minerals are mostly electrums and argentites,and some occur in tetrahedrite with isomorphism form. Gold and silver are mainly carried by pyrite,arsenopyrite,galena,cerussite and so on.The research on the occurrence of gold and silver will provide reference for the design of mineral processing processes.
