某多金属矿床中银的物相分析方法研究

根据电子探针能谱分析，相关分析，镜下鉴定及各单矿物分析结果，银绝大部份呈固溶体分散赋存于方铅矿，铜矾，铅铁矾等铅的含氧酸盐矿物中。在砂矿和岩矿中的银，铅大部份不呈矿物状态，分散状态存在于褐铁矿和锰结核中，本方法既适合该矿的各种矿石分析，也适合用于该矿选矿产品的银物相分析。

Study on method of phase analysis of silver in a certain complex deposit

According to the conclusions made from the analysis of energyspectrum, interrelation analysis, microscopic appraisal and monomineral analyses,the great majority of silver are in a state of solid solution occurred dispersively in lead mineral of oxy-acid salt, such as galena, lead vitriol, leadiron vitriol etc. The greater part of silver and lead in alluvial ore and lodeore are not in mineral state, but in dispersive state occurred in limonite andmanganese nodule.This method is suitable both for the analyses of various oresand silver phase analysis of ore dressing product in this deposit.
