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 . In order to comprehensively recover the valuable elements such as gold and copper from complex and refractory gold polymetallics by using the oxidized enhanced flotation process, the results show that when w (Cu) = 1.90%, w (Au) = 3.92 g / t, the oxidation time of 1 0 min, the better separation of copper and sulfur can be achieved copper grade 11.51.1%, recovery 77.48% ~ 77.72%, gold 3 6.35 ~ 3 8.42 g / t, the recovery rate of 5 9.0 0% ~ 62 .3 5% qualified copper concentrate.
