摘　　要：针对澳炉缓冷渣的性质特点,从炉渣冷却制度、磨矿细度、浮选药剂等方面考查了对选铜指标的影响,提出了最佳选铜技术条件。闭路试验表明,采用阶段磨矿阶段选别工艺,可获得铜精矿铜品位16.11%,回收率69.90%比较理想的技术指标。实现了澳炉炉渣的综合再利用,这对经济、社会和环境效益都具有十分重要的现实意义。According to the mineral properties of Ausmelt copper smelting slag, the effects of slag cooling system, grinding fine- ness and floatation reagent on copper concentration index have been investigated. The results show that, applying the stage grinding and stage beneficiation process, 69.90% Cu was recovered in one stage flotation and 16.11% grade of Cu concentrate was achieved. With fairly good economic, social and environmental benefit, the multiple utilization of this copper slag has been achieved.
