摘要
Abstract
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 .关键词
