摘    要:介绍了西北某难浸金矿堆浸尾矿利用的试验结果,先采用浮选工艺,获得产率4.09% 、金品位64.72g/t、回收率70.77% 的浮选精矿;浮选精矿经焙烧后氰化浸出,金浸出率达95.73% ;浮选尾矿直接氰化浸出,金的浸出率可再增加14.10% ,从而获得金总收率81.85% 的优异指标。初步技术经济分析结果表明,采用本文介绍的方法利用该类尾矿资源,经济效益较好。

关 键 词:堆浸尾矿  浮选  氰化

Abstract:The experimental results of comprehensive utilization of heap leaching tailings from a refractory gold ore were described.The experimental procedure used included:firstly,by use of flotation technology produced a flotation concentrate,then,roasting of the flotation concentrate and cyanidation leaching of calcine,finally direct cyanidation of flotation tailings.The satisfactory total gold recovery of 81.85% was obtained.The technical economic analysis showed that authors proposed flowsheet of comprehensive utilization of tailings can gained better economic profit.
Keywords:Heap Leaching Tailings  Flotation  Cyanidation
