摘    要：利用透射电子显微象、电子衍射和X射线能量色散谱仪研究了黄铁矿、毒砂、石英等矿物中次显微金的赋存状态及其颗粒大小,扩大了寻找金矿床的范围为全矿的综合开采、选矿流程设计及提高金的回收率等方面提供了技术依据。

Abstract: The existent states and particle sizes of submicro-gold in pyrity, arsenopyriteand quartz ores are studied by TEM imaging、electron diffraction and EDS.This work has enlarged the range of seeking gold mine, provided technicaldemenstration for comprehensive exploitation, design of mineral concentratonflow and the improvement of collecting rate of gold mine and so on.
