| 摘 要： | 湖南湘西金矿在长期的开采过程中产生了大量的尾矿，其中堆存时间最长的一号尾矿库中，金发生了显著的次生成矿作用，次生矿体平均金品位５．９２ｇ／ｔ，平均厚度１１．７７ｍ，可达小－中型金矿床规模。水化学分析、热力学分析和模拟实验表明，尾矿－水的相互作用导致了尾矿中金的溶解，迁移和次生成矿作用。

| Abstract: | Large amounts of tailings were produced during the long-time mining practice in the Xiangxi gold mine,Hunan,China. There occurred marked secondary metallogeny of An in the No. 1tailing reservoir which has been stored up for the longest time. In secondary ore body,the averagegrade of An is 5. 92 g/t and the average thickness is 11. 77m,and it can be a small-moderate deposit. Chemical analyses of water,thermodynamics and experiments show that the interaction between tailings and water has caused the dissolution,transport and secondary metallogeny of An in tailings. |
