摘要
采用硫酸直接浸出铅锌烟尘,考察硫酸浓度、液固比、浸出时间和温度对锌浸出率及铅入渣率的影响。结果表明,在下述优化浸出条件下,锌浸出率达93.55%,铅入渣率92.01%:硫酸浓度175g/L、液固比6∶1、浸出时间60min、浸出温度60℃。
Pb-Zn bearing dust was directly leached by sulfuric acid. The effects of H2 SO4 concentration, ratio of liquid to solid （L/S）, leaching time and temperature on zinc leaching rate and rate of lead going into leaching residue were investigated. The results show that the zinc leaching rate is 93.55% and the rate of lead going into leaching residue is 92.01% under the optimum conditions including H2SO4 concentration of 175 g/L, L/S=6 ： 1, leaching duration of 60 min and leaching temperature of 60℃.
