针对复杂难选铜锌硫化矿的浮选分离难题，结合实际矿石开展研究，根据矿石的特点，提出以酯－１０５作捕收剂，以疏酸锌和ＮａＨＸ混合作闪锌矿的抑制剂，采用抑锌浮铜、铜粗精矿再磨精选工艺，取得理想的铜锌分离浮选指标。新工艺用于生产实际，圆满解决了铜精矿含锌超标的问题，创造了良好的经济效益。 Aiming at the difficult flotation separation problem of complex refractory copper-zinc sulfide ores, combined with the actual ore research, according to the characteristics of ore, we proposed the ester-105 as collector and the sparse zinc blende and NaHX as sphalerite inhibitor, The use of zinc suppression float copper, copper rough concentrate grinding process, to achieve the ideal copper-zinc separation flotation index. The new process for the actual production, the successful solution to the copper concentrate exceeded the issue of zinc, and create a good economic benefits.
