摘　　要：研究了用盐酸从炼铅厂烟化段产出的锌烟尘中浸出分离铅和锌,考察了液固体积质量比、盐酸浓度、浸出温度和浸出时间对铅、锌浸出率的影响,确定了最佳浸出参数。试验结果表明:在浸出温度80℃、液固体积质量比8∶1、盐酸浓度6mol/L最佳条件下,铅和锌的浸出率均大于90%。Leaching of lead and zinc from zinc dusts coming from fuming stage in lead smelter were studied using hydrochloric acid. The effects the ratio between liquid volume and solid mass, concentration of acid, leaching temperature and leaching time on zinc and lead leaching rates were examined. The results show that under the best conditions of the ratio between liquid volume and solid mass of 8 ： 1,leaching temperature of 80 ℃ and HCI concentration of 6 mol/L,the leaching of lead and zinc are both more than 90 %.
