Sustainable Mining and Metallurgy

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.
