摘要
在铜矿石工艺矿物学分析的基础上 ,研究柏坊铜矿 5 40 1残矿的原地破碎浸出采铜方案。选择氧化矿与硫化矿的浸矿剂、泥质矿石浸出添加疏松物 ,采取负压浸出及矿块底部排泥措施 ,改善泥质铜矿石渗透性和可浸性。结果表明用原地破碎浸出采矿法回收 5 40
The recovery of residual low grade copper ore body in Beifang Copper Mine by in situ fragmentation-leaching process is investigated on the basis of the mineralogy study of the copper ore The penetrability and leachability of the muddy copper ore are improved by selection of appropriate leachate for sulfide and oxide copper minerals and loosening agent for muddy ore, and vacuum application to leaching, and the mud discharge measures at the bottom of the stope The results show that it is feasible in technology to recovery residual low grade copper ore body by the in situ leaching process
