摘　　要：采用某铜冶炼企业的选矿现场浮选工艺流程,开展对铜冶炼产生的闪速炉渣和转炉渣性质研究,并对不同配比条件下混合炉渣进行浮选试验,研究两种炉渣不同配比对铜浮选回收率的影响。结果表明:闪速炉渣铜品位为1.51%,转炉渣中铜品位为5.92%。闪速炉渣中铜主要存在形式为硫化铜,占总铜量的82.12%,金属铜和氧化铜以及其他含量相对较少;转炉渣中铜主要存在形式为硫化铜和金属铜,硫化铜含量占总铜量的54.73%,金属铜含量占总铜量的34.80%,氧化铜以及其他铜含量相对较少。闪速炉渣与转炉渣的配比为1:4时获得较好的浮选指标,混合炉渣浮选铜回收率为94.78%,尾矿品位为0.34%。The characteristics of flash furnace slag and converter slag produced by copper smelting were studied using the flotation process in the field of a copper smelting enterprise, and the flotation test of mixed furnace slag was carried out under different mixing ratio. The results show that the copper grade of the slag of the flash furnace is 1.51% and that of the converter slag is 5.92%. The main form of copper in flash furnace slag is copper sulfide, accounting for 82.12 % of total copper content. The main forms of copper in converter slag are copper sulphide and copper metal. The main forms of copper in converter slag are copper sulphide and copper metal. The copper sulphide content accounts for 54.73%, and the metal copper content accounts for 34.80% of the total copper content. The copper oxide content and other copper content are relatively small. Good flotation indexes were obtained when the ratio of the flash slag to the converter slag was 1:4, the recovery of copper flotation from the mixed slag was 94.78%, and the tailing grade was 0.34%.
