安徽铜陵某矿为一大型含金铜硫铁矿床.其中伴生金的储量已达大型金矿床,有重要的综合利用价值.伴生金中的次显微金,因其颗粒微小,分布不均匀,故用矿相显微镜难以研究.本次工作通过透射电镜、扫描电镜和电子能谱分析等手段,对矿床中的显微金及次显微金进行了观察分析,初步查明了其赋存状态,并证实透射电镜、扫描电镜及电子能谱分析是研究次显微金的有效手段.
An ore deposit in Tongling, Anhui Province is a large gold-copper-copper pyrite deposit, in which associated gold reserves have reached large-scale gold deposits, which have important comprehensive utilization value. The secondary minor micro-gold in associated gold has small particles and uneven distribution , So it is difficult to study with the mining phase microscope.This work through transmission electron microscopy, scanning electron microscopy and electron spectroscopy analysis and other means of deposit in the micro-gold and sub-micro-gold were observed and analyzed initially identified its occurrence State, and confirmed by transmission electron microscopy, scanning electron microscopy and electron spectroscopy analysis is an effective means of sub-micro-gold.
