铜冶炼炉渣缓冷技术研究与生产实践

Copper Smelting Slag Slow Cooling Technology Research and Practice

国内铜冶炼厂广泛采用缓冷工艺回收炉渣中铜,该工艺可以提高冶炼厂铜回收率和冶炼炉对原料的适应性。缓冷炉渣经过选矿后,铜精矿返回冶炼系统,尾矿作为生产水泥的原料。介绍了铜冶炼炉渣缓冷工艺及生产实践中存在的主要问题,进行了原因分析并提出了解决措施。

Slow cooling process is widely used to recycle copper from slag in domestic copper smelter, which can improve copper recovery rate and adaptability of smelting furnace to raw material. After slow cooling slag beneficiation, copper concentrates return to the smelting system, tailings is to be as the raw material for cement production. In this article, the slow cooling process of copper smel-ting slag and the main problem in production practice are described, s the reasons are analyzed and solutions are proposed.
