摘　　要：介绍了以三氯化铁作氧化剂,氯化钠提供氯离子,用盐酸从高温氧化后的铅阳极泥中浸出铋、锑,考察了氧化温度、盐酸浓度、浸出温度、反应时间、液固体积质量比、三氯化铁和氯化钠用量对铋、锑浸出率的影响。试验结果表明:铅阳极泥预处理对铋、锑浸出率影响较大;铅阳极泥粉磨过200目筛,在氧化温度220℃、盐酸浓度5mol/L、液固体积质量比5∶1、反应温度80℃、反应时间3h、三氯化铁质量浓度10g/L、氯化钠质量浓度45g/L条件下,铋、锑浸出率分别为99.44%和99.69%,浸出效果较好。Leaching of bismuth and antimony from lead anode mud oxidized at high temperature using hydrochloric acid as leaching agent ,ferric chloride as oxidant ,sodium chloride to provide more chloride ions was investigated .The effects of oxidizing temperature of lead anode mud ,hydrochloric acid concentration ,leaching temperature ,reaction time ,ratio between liquid volume and solid mass ,the amount of ferric chloride and sodium chloride on leaching of bismuth and antimony were examined . The experimental results show that the pretreatment for lead anode slime has a greater influence on the leaching of bismuth and antimony .Under the conditions of hydrochloric acid concentration of 5 mol/L ,ratio betw een liquid volume and solid mass of 5∶1 ,leaching temperature of 80 ℃ ,reaction time of 3 h ,ferric chloride concentration of 10 g/L ,sodium chloride concentration of 45 g/L ,the leaching of bismuth and antimony reach 99 .44% and 99 .69% respectively for the lead anode mud oxidized at 200 ℃ and through 200 mesh sieve .
