湿法炼锌中锌铁分离方法与运用探讨

Discussion on Separation Method and Application of Zinc and Iron in Zinc Hydrometallurgy

湿法炼锌已成为锌冶炼的主流趋势,铁闪锌矿作为当今锌冶炼的主要原料,铁的分离成为其在湿法炼锌过程中的关键环节,湿法炼锌工艺流程的选择很大程度上就是锌铁分离方法的选择。阐述了铁闪锌矿在湿法炼锌过程中几种主要的锌铁分离方法及其工艺原理、工艺控制条件、主要经济技术指标,并且分析了工艺的优缺点,为湿法炼锌企业锌铁分离方法的选择和运用提供依据。

Zinc hydrometallurgy has become the mainstream trend of zinc smelting.Sphalerite is main raw material of zinc smelting,iron separation has become a key link in zinc hydrometalluegy.Choice of zinc smelting process is largely choice of zinc-iron separation method.Several main zinc-iron separation methods and process principles,process control conditions,and main economic and technical indicators of zinc hydrometallurgy process of sphalerite were described.Advantages and disadvantages of those processes were analyzed which can provide reference of selection and application of zinc-iron separation methods.
