采用炼铜烟灰制取硫酸锌，研究了批式滴加酸浸取锌和两段除铁工艺．实验结果表明：用批式滴加法浸取，锌浸取率≥98％、铜浸出率≥96％，铁浸取率可控制在0．02％以下．其工艺条件为：液固质量比3∶1，温度80～90℃，酸浸液中硫酸加入量39g／L，滴酸时间1．5h，浸取时间2h．采用先通氧（或鼓空气）氧化，再加过氧化氢深度氧化除铁工艺，溶液最终铁含量≤0．01g／L．制得的硫酸锌可用于电解． Smelting copper soot was used to prepare zinc sulfate. The batch acid leaching of zinc and the two-stage iron removal process were studied. The experimental results showed that the leaching rate of zinc was ≥98%, the leaching rate of copper was ≥96% and the leaching rate of iron was less than 0.02%. The process conditions are as follows: liquid-solid mass ratio of 3: 1, temperature of 80-90 ° C, the amount of sulfuric acid added in the acid leaching solution 39g / L, the time of dripping acid 1.5h and the leaching time 2h. The first oxygen (or drum air) oxidation, coupled with the depth of hydrogen peroxide oxidation process, the final solution iron content ≤ 0.01g / L. The resulting zinc sulfate can be used for electrolysis.
