| 摘 要： | 黑色岩系金矿床具有重要的经济价值，滩间山金矿床为多因复成成因，黄铁矿是其最主要的矿石矿物。穆斯堡尔诺分析和金的浸取实验表明：滩间山金矿的黄铁矿中除存在大量金矿物（自然金或银金矿）外，尚存在１．２７％的晶格金，这部分金是一种潜在的金矿资源。此外，文中还探讨了晶格金的形成机理。

| Abstract: | Why is pyrite always a gold-rich mineral? This problem has still been argued at presetn.It has ben studied in this paper by means of simulated test. The auhors think that chemical adsorption is the primary factor that gold always enters paste. In normal pressure and HCL-H2O auriferous system, the adsorption process of pyrite can be divided into two stages elearly as tiom acs on. Mathematical model of adsorption curve (C-t relationship) is C=0. 55-0.312(1-2). |
