中文摘要: 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175 g/L、液固比6∶1、浸出时间60 min、浸出温度60 ℃。
Abstract:Pb-Zn bearing dust was directly leached by sulfuric acid. The effects of H2SO4 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 ℃.
