镀锌灰的热酸浸出和除铁试验研究
Research on Leaching of Zinc Using Hot Acid From Zinc Ash and Removal of Iron From Leaching Solution by Jarosite Process
摘要
Abstract
By single factor experiments ,leaching of zinc using hot acid from zinc ash and removal of iron from the leaching solution by jarosite process were researched .The results show that the optimum conditions for leaching zinc are determined as follow s initial acid concentration of 150 g/L ,leaching temperature of 90 ℃ ,ratio between liquid volume and solid mass of 6∶1 .At the optimum conditions , the leaching rate of zinc is more than 97% .Removal of iron is over 98% under the conditions of temperature of 90 ℃ ,reaction time of 3 h .关键词
