| 摘 要： | 锌湿法冶炼渣酸性浸出液中铁含量通常较高,分别以空气、双氧水和二氧化锰为氧化剂,对氧化中和除铁的效果进行比较,并研究了双氧水氧化中和除铁法中pH和反应温度对除铁效果的影响。结果表明,双氧水氧化中和除铁法是最佳的除铁方法,常温下pH 5以上除铁效果较好,除铁效果随温度升高而增强,且过滤性能较好。

| Abstract: | The iron content in acidic leaching solution of zinc hydrometallurgical residue was usually high. The iron removal effects of oxidation-neutralization process were compared with different oxidant including air, hydrogen peroxide (H2O2) and manganese dioxide (MnO2). The effects of pH and temperature on iron removal of H2O2-oxidation-neutralization process were investigated. The results show that H2O2-oxidation-neutralization process is the optimum way of iron removal, and with the increasing of temperature, the iron removal rate increases with better filtrating. |
