摘要 某低品位铜锌混合精矿含锌41.86%、铜4.52%,一直以来都作为锌精矿折价出售,没有回收其中的铜,造成了资源浪费。采用BK302为捕收剂的抑锌浮铜方案,通过一次粗选、三次精选和三次扫选浮选工艺获得铜精矿和锌精矿,实验室闭路试验指标为:铜精矿含Cu 20.67%、Zn 6.12%,铜回收率85.25%;锌精矿含Zn 50.05%、Cu 0.82%,锌回收率97.27%,既回收了铜,又提高了锌精矿品位。 Certain low-grade copper-zinc mixed concentrate contains 41.86%zinc and 4.52%copper.It had been sold as zinc concentrate at a discount price for a long time,and the copper in the concentrate had not been recovered,resulting in a waste of resources.In this study,copper and zinc were recovered by one roughing,three scavenging and three cleaning processes using BK302 as collector.The results of lockedcircuit test are as follows:copper concentrate of Cu 20.67%and Zn 6.12% with copper recovery 85.25%;zinc concentrate of Zn 50.05% and Cu 0.82% with zinc recovery 97.27%.The copper was recovered.At the same time,the quality of zinc concentrate was improved.
