Efficient separation method for sodium sulfide and carnallite in antimony hydrometallurgy electrodeposition waste liquid

The invention discloses an efficient separation method for sodium sulfide and carnallite in an antimony hydrometallurgy electrodeposition waste liquid, and relates to the field of hydrometallurgy. According to the method, carnallite and sodium sulfide are effectively separated from an electrolytic solution in an evaporative crystallization separation mode, so that the carnallite is removed, the influence of the carnallite on the production process is reduced, and the leaching rate and the electrolysis effect are improved; and the carnallite and the sodium sulfide in the electrodeposition waste liquid are efficiently separated, so that the influence of the carnallite and the sodium sulfide and byproducts thereof on production and raw materials is avoided, and the leaching rate and the electrolysis efficiency are improved. 本发明公开了一种湿法炼锑电积废液中硫化钠与杂盐的高效分离方法，涉及湿法冶金领域。本发明通过蒸发结晶分离的方式有效的将杂盐和硫化钠从电解液中分离，去除了杂盐减少了杂盐对于生产工艺上的影响，提高了浸出率和电解效果。实现高效的将电积废液中的杂盐和硫化钠进行分离，从而避免二者及其副产物对生产和原料的影响，提高浸出率和电解效率。
