摘　　要：湿法炼锌技术是当前锌冶炼的主要技术形式,该技术的特点表现在直接氧压浸出硫化锌精矿,常压富氧直接浸出硫化锌精矿,高效大型设备,综合回收和无害化处理浸出渣,自动控制工艺系统等几个方面。本文以湿法炼锌为背景,考察了输氧管安装前后,搅拌速度、温度、氧分压等条件对氧气溶解行为的影响,通过数据对比验证氧溶解率的提高可加快锌的浸出速率。The technology of zinc hydrometallurgy is the main form of current technology of zinc smelting, the characteristics of the technology on oxygen pressure leaching of zinc sulphide concentrate, atmospheric oxygen direct leaching of zinc sulfide concentrate, high efficiency and large scale equipment, leaching slag comprehensive recycling and harmless, automatic control technology, system and other aspects. Based on the background of wet zinc, were investigated before and after installing the oxygen tube, stirring speed, effect of oxygen partial pressure conditions on the oxygen dissolution behavior, by comparing the data validation to improve the rate of dissolved oxygen can improve the leaching rate of zinc.
