摘要： 为改善大冶铜绿山坑采难选矿石的选铜指标，进行了较详细的实验室浮选试验。结果表明：混合捕收剂有利于提高铜的回收率；添加调整剂SB-1可较好地解决云母类脉石对铜浮选的的干扰问题；将异丁黄药与丁铵黑药按2∶1比例混合作为混合捕收剂，采用添加SB-1的中矿再磨闭路流程，可获得精矿铜品位20.51%、铜回收率93.37%、金品位12.48 g/t、金回收率73.60%的较好选铜指标。

Abstract: In order to improve the copper beneficiation performance of the refractory ore from Daye Co.'s Tonglushan Open-Pit Mine, detailed laboratory flotation test was made. The results show that mixed collector can be beneficial to the improvement of copper recovery, addition of SB-1 regulator can well solve the interference of mica type gangues to the copper flotation. The application of the collector mixed by isobutyl xanthate and butylammonium aerofloat in 2∶1 ratio and SB-1 in the flowsheet including closed-circuit middling regrinding obtained rather good copper separation indexes. The concentrate has a copper grade of 20.51%, copper recovery of 93.37%, gold grade of 12.48 g/t and gold recovery of 73.60%.

Key words: Refractory ore from open-pit mining, Copper separation, Mixed collector, Regulator SB-1, Middling regrinding
