摘要
含金的低品位粉矿、表外矿、尾矿、含粘土质矿及其他工业副产的含金物料(如硫铁烧渣)等用常规堆浸法处理时因渗透性不好,容易产生沟流或板结而使浸出率不理想。所以堆浸法的改革方向是改善物料的渗透性能,其中制粒—堆浸工艺是解决这一技术难题行之有效的方法。
The Study and experiment of agglomeration-leaching method of Lowgrade oxidized fines at Longmang Mt.Gold Mine,Hunan Province has been Completed by the Solution Group of Changsha Institute of Mining Research and got a better result.The extraction rate of gold reached at 85%,While the lea- ching cycle only took 15 days.
