摘要
介绍了紫金山金矿矿床赋存的基本特征。为了开发利用紫金山金矿低品位资源 ,加强了矿山地质工作 ,将坑采转为大规模露天开采 ,挑块分级排除废石提高了入选品位 ;利用矿石氧化程度较高的特点 ,采用破碎—洗矿—堆浸 (或炭浸 )选矿工艺取得了良好的技术经济指标。
The basic characteristics of gold deposit were introduced in the paper. In order to exploit and utilize gold resources with lower grade in Zijinshan Mine and strengthen geological management in the mine, a large scale of open mining was adopted instead of underground mining. The grade of mined gold ores can be improved effectively with picking, classification and discharging waste. Based on high extent of oxidation of the ores, with the dressing process of 'crushing-washing-heap leaching or carbon-in-leach', good technical and economic indexes can be reached.
