新老金厂金矿地质特征及低品位矿石开发利用

Geologic Feature and Utilization of Low-grade Ore in Xinlaojinchang

新老金厂金矿位于塔里木-中朝板块内北山陆缘活动带,俞井子-柳园陆内复式裂谷带中。为延长新老金厂金矿的矿山寿命,急需对低品位金矿石进行开发利用,通过开采低品位氧化金矿石,以大块度、大堆高低成本堆浸法处理新老金厂矿区氧化金矿石,经过工业堆浸实践证明能取得较好的经济效益,扩大了新老金厂金矿矿山可利用资源的范围和资源量,为北山地区低品位金矿资源的利用提供了一种行之有效的方法。

Xin-LaoJinChang is situated in Beishan epicontinental mobile belt of Sino-Korean plate and YuJingZi -LiuYuan Intracontinental duplex rift zone .By exploitation of low-grade oxidized gold ore , can Improve the utilization of Low-grade gold ore ,and prolong the mine life of Xinlaojinchang , The practice has proved that by the methods of low-cost heap leaching method processing the gold oxide ore of Xin-LaoJinChang mining area can achieve better economic efficiency .By the above method we can expand the range and amount of available resources of the mine and provides an effective method to use the low grade gold mine at the area of Beishan .
