摘　　要：主要介绍应用电子探针研究某锰银矿矿物,通过电子探针研究了某地锰银矿矿物成分,银的赋存状态等。研究结果表明,该锰银矿以锰榍石和针铁矿为主,含方解石、石英等脉石矿。矿样中的锰矿、铁矿、铅矿、锌矿、砷矿等矿物为细粒状相互伴生矿物,银主要以元素形态赋存在锰矿物中,自然银和辉银矿在锰银矿中微量,粒度小于5μm。A study on a silver-manganese ore by electronic microprobe was introduced, in which the mineral constitution of the mentioned ore and silver occurrence state were investigated. The results show that the silver - manganese ore mainly contain the manganese sphene and goethite, as well as other gangue such as calcite and quartz. Manganese, iron, lead, zinc, arsenic and other minerals in the ore appear fine grain and they are mutual associated minerals. Silver is mainly in the form of silver element and exists in manganese minerals. Natural silver and argentite in the ore are trace and their particle size are less than 5μm.
