| 中文摘要: |
| 本文对湖南黄金洞金矿主要载金矿物毒砂进行了金含量、X射线衍射、电子探针、扫描和透射电镜、电子顺磁共振波谱及穆斯堡尔谱等系统分析研究.结果表明,含金毒砂在成分上及结构上都明显地偏离理想毒砂;金含量高而稳定;毒砂中的铁为Fe3+;金主要呈晶格金存在,以类质同象形式置换毒砂中的砷. |
| 英文摘要: |
| Arsenopyrite is the main gold-bearing mineral of Huangjindong gold deposit in Hunan Province.Determinations of chemical composition,X-ray diffraction,electron microprobe,EPR and Mossbauer analysis show that the arsenopyrite in huangjindong gold deposit is different obviously from the ideal arsenopyrite in composition and structure.The content of gold is high and stable in the former; iron,occuring as Fe ± 3; gold,as solid solution in crystal lattice and replacing arsenic isomorphically. |
