摘　　要：本文介绍了粗铅中铜金属综合回收采用的火法工艺,分析了不同生产工艺的优缺点,并对粗铅中铜金属回收工艺提出了展望,指出铜浮渣富氧熔池熔炼工艺、铜浮渣低温氧化熔炼工艺和粗铅连续精炼脱铜工艺具有较好的应用前景,粗铅初步火法连续精炼脱铜工艺在解决粗铅含砷量高、铅冰铜含铅量高、原料室和循环锅长炉结等影响技术推广的问题之后,将成为粗铅中铜金属综合回收的主流工艺。This paper introduced the pyrometallurgical process used in the comprehensive recovery of copper metal in crude lead,analyzed the advantages and disadvantages of different production processes,and put forward the prospect of the recovery process of copper metal in crude lead.It is pointed out that the copper scum oxygen-enriched bath smelting process,copper scum low-temperature oxidation smelting process and crude lead continuous refining copper removal process have good application prospects.After solving the problems of high arsenic content in crude lead,high lead content in lead matte,long furnace junction in raw material room and circulating boiler,the preliminary pyrometallurgical continuous refining copper removal process of crude lead will become the mainstream process of comprehensive recovery of copper metal in crude lead.
