摘要
为了从多金属复杂难选金矿中综合回收金、铜等有价元素 ,采用氧化强化浮选工艺 ,在原矿 w(Cu) =1 .0 9%、w(Au) =3 .92 g/ t的情况下 ,充气氧化时间为 1 0 min时 ,可较好地实现铜硫分离 ,可获得铜品位1 5 .1 1 %、回收率 77.48%～ 77.72 % ,含金 3 6.3 5～ 3 8.42 g/ t、回收率 5 9.0 0 %～ 62 .3 5 %的合格铜精矿 .
Valuable elements of gold and copper in difficult flotation a polymetallic gold mine can be effectively recovered by means of an oxidization aggrandizement flotation process.The copper concentrate containing 15.02%~15.11% of Cu and 36.35 g/t^38.42 g/t of Au have been obtained from the ore containing 1.09% of Cu and 3.92 g/t of Au and the recovery is 77.48%~77.72% for Cu and 59.00%~62.35% for Au respectively.
