摘　　要：研究了用硫酸从铅冶炼水淬渣中浸出铁。考察了硫酸质量浓度、浸出温度、浸出时间对铁浸出率的影响。试验结果表明,用硫酸浸出铁,在硫酸质量浓度175g/L、浸出温度60℃、浸出时间60min最佳条件下,铁浸出率达73.85%。Leaching of iron from water‐quenched slag in lead smelting using sulfuric acid was researched .T he effects of sulfuric acid concentration ,leaching temperature and leaching time on leaching of iron were examined .The results show that under the optimum process conditions of sulfuric acid concentration of 175 g/L ,leaching temperature of 60 ℃ and leaching time of 60 min , leaching rate of iron is up to 73 .85% .
