由锌-铅鼓风炉出来的铅所产生的铜-铅浮渣主要是金属铜,而铅鼓风炉的浮渣则含硫化铜高些。ISP公司已研制出两种湿法冶金工艺处理锌-铅鼓风炉铜浮渣。第一种为硫酸浸出、电积法,已用于杜依斯堡的贝泽留斯工厂。第二种方法为氨浸,溶剂萃取,产出高品位硫酸铜溶液,用以制作优质硫酸铜或电铜。这些是本文的主题。铜的选择性浸出是在弱活性条件下进行的,铜以外的各种离子残留在过滤后的浸出渣
Copper produced by lead from a zinc-lead blast furnace - lead scum is predominantly metallic copper, whereas lead blast furnace scum contains higher copper sulphide. ISP company has developed two kinds of hydrometallurgical process zinc-lead blast furnace copper scum. The first is sulfuric acid leaching, electrowinning method, which has been used in Duisburg Fort Beireli factory. The second method is ammonia leaching, solvent extraction, production of high-grade copper sulfate solution for the production of high-quality copper sulfate or copper. These are the topics of this article. Selective leaching of copper is carried out under weakly active conditions, and various ions other than copper remain in the leached slag after filtration
