Abstract

本发明提出了一种含氯氧化锌二次物料的处理方法，包括如下步骤：1)将含氯氧化锌二次物料Ⅰ用酸性溶液浸出；2)用P204-煤油溶剂选择性萃取锌；3)进行反萃-电解回收锌；4)循环操作1)-4),使氯、钾、钠、镁等富集，形成氯盐-硫酸盐混合体系；5)将步骤4)得到的萃余液开路，当氯离子投入和开路平衡，将开路萃余液与含氯氧化锌二次物料Ⅱ混合，再进行液固分离，分离的沉积物加入步骤1)用酸性萃余液浸出；6)当分离出的溶液达到预定条件时，将含氯水相进行除杂；7)蒸发浓缩，分别结晶产出KCl和NaCl产品。本发明环保节能，无工艺废水排放，大幅度降低生产成本，彻底消除目前脱氯工艺带来的次生污染。
