摘　　要：针对我厂生产的含铅0.2%~0.4%粗铜,本文结合生产实际,根据除铅的热力学和动力学理论基础,选择SiO2作为脱杂剂,在精炼的氧化阶段,利用压缩空气将装入压力容器中粉状SiO2喷入溶体底部造渣,再进行放渣达到除铅目的,本文介绍了具体操作过程,得到精炼各阶段的相关生产数据。Regarding the crude copper with lead content ranging from 0.2%to 0.4%produced by our factory,this article combines production practice and selects SiO2 as the impurity removal agent based on the thermodynamic and kinetic theory of lead removal.In the refining oxidation stage,compressed air is used to spray powdered SiO2 into the bottom of the solution to form slag,and then slag is discharged to achieve the goal of lead removal.This article introduces the specific operation process and obtains relevant production data for each refining stage.
