摘要/Abstract

摘要： 江苏苏钢集团电弧炉炼钢烟尘含锌15.4%，并主要分布在铁酸锌中。对该炼钢烟尘进行浸出试验，结果表明：以氢氧化钠为浸出剂进行碱性浸出时，锌的浸出率仅为34.0%；以硫酸为浸出剂进行酸性浸出时，在搅拌转速为420 r/min，硫酸浓度为200 g/L，液固比为10∶1，反应温度为90 ℃，浸出时间为2 h的条件下，锌的浸出率达到98.7%。

Abstract: The electric arc furnace dust in Jiangsu Sugang Group contains Zn content of 15.4% and is mainly embedded in zinc ferrite. Results of the leaching tests on this dust showed that only 34.0% of zinc was extracted when sodium hydroxide as lixiviant in alkaline leaching. And about 98.7% of zinc was leached out with sulphuric acid as lixiviant under the experimental conditions of stirring at 420 r/min, 200 g/L of H2SO4, reaction temperature 90 ℃, liquid to solid ratio 10∶1 and reaction time 2 h.
