| 摘 要： | 不可见金存在于世界许多金矿的黄铁矿中。本文以冀东金厂峪金矿为例，对黄铁矿中不可见金的存在形式进行了多种实验方法的研究。黄铁矿金含量的多点分析和扫描电子显微镜实验研究表明，黄铁矿中不可见金大部分是呈链状排列的超显微金（粒度小于0.5μm的自然金）。黄铁矿的分步溶解实验、电子顺磁共振（EPR）及穆斯鲍尔谱研究证实黄铁矿中12.96％的不可见金以离子状态进入黄铁矿晶格代替Fe2 。

| Abstract: | Invisible gold occurs in pyrite of many gold deposits in the world. The mode of occurrence ofinvisible gold in pyrite was examined by a variety of experimental methods in this paper. Poly-spotanalyais of invisible gold in pyrite and SEM examination showed that the invisible gold in pyrite is,for the most part, submicroscopic in size and arranged in a chain. Part of the invisible gold(12.96% ) substituted Fe2 in the lattice of pyrite in the form of Au , as indicated by step-dissolutionexperiments, EPR and Mossbauer studies of pyrite. |
