| 摘 要： | 在Ａｕ（Ⅲ）－Ｃｌ络合溶液和常温常压条件下，黄铁矿随时间（ｔ）变化对金吸附的动态实验表明：整个吸附过程明显分为两个阶段．前一个阶段是快速达到平衡的吸附过程，随着平衡的建立，金的沉淀速度迅速变小，随后即进入缓慢吸附阶段，溶液中金的浓度按指数函数关系衰减．不同粒度黄铁矿实验结果的横向比较显示，粒度越细，金的沉淀速度越快，沉淀金的总量也越多。

| 关 键 词： | 黄铁矿，Au（Ⅲ）－Cl络合溶液，吸附过程，沉淀速度，金的成矿机理 |

| Abstract: | Why is pyrite always a gold-rich mineral? This problem has still been argued at presetn. It has been studied in this paper by means of simulated test. The authors think that chemical adsorption is the primary factor that gold always enters pyrite. In normal pressure and HCL-H2O auriferous system, the adsorption process of pyrite can be divided into two stages clearly as tiom goes on. Mathematical model of adsorption curve (C-t relationship) is C=0. 55e-0. 312(t-2). |
