中文摘要: 采用硫酸为浸出剂，对高炉炼铁烟尘进行未活化和活化浸出工艺研究。通过正交试验与单因素试验相结合考察硫酸浓度、浸出温度、浸出时间、液固比对烟尘中锌浸出率的影响。结果表明，未活化的烟尘在液固比8∶1、硫酸浓度170 g/L、浸出温度95 ℃，浸出时间90 min时，锌浸出率达到96.78%；而经活化的烟尘在液固比7∶1、硫酸浓度150 g/L、浸出温度85 ℃，浸出时间75 min时，锌浸出率达到98.19%。
Abstract:Blast furnace dusts were non-activation and activation leached with sulfuric acid. The effects of sulfuric acid concentration, leaching temperature, leaching time, and ratio of liquid to solid on zinc extraction rate were investigated by orthogonal experiment and single-factor experiment. The results show that zinc leaching rate from non-activated dusts is 96.78% under the conditions including ratio of liquid to solid of 8∶1, sulfuric acid concentration of 170 g/L, leaching temperature of 95 ℃ and leaching time of 90 min. To compare, zinc leaching rate from activated dusts is 98.19% under the conditions including ratio of liquid to solid of 7∶1, sulfuric acid concentration of 150 g/L, leaching temperature of 85 ℃ and leaching time of 75 min.
