摘要
利用日立H-800型透射电子显微镜(附EDAX能谱仪)研究了泰国某锑金矿床及湖南新邵龙山锑金矿床的毒砂中次显微金的赋存状态,发现自然金常以粒径小于0.2μm的小圆球状出现。
In tecent years, on the basis of studies on the occurrence manner ofsubmicoro-gold in arsenopyrite of a certain stibium-gold deposit in Thailandand of the Longshan gold deposit in Xinshao county of Hunan using modelHitachi H-800 Transmission Electron Microscope (attaching EDAX energyspectrometer) the authors have discovered that the gold occurs usually insmall balls of its natural form with a size of less than 0.2 micron.
