| 摘 要： | 采用N235萃取含氟、氯的锌浸出液,氟、氯被萃取到有机相中,锌留存于萃余液中,锌萃取率低于5%,氟脱除率高于80%,氯脱除率高于94%。在N235有机相中加入异辛醇,萃取、水洗、反萃温度控制在40~45℃,可避免出现有机相乳化和分相时间长的问题。萃余液中锌、氟、氯浓度分别为55.54、0.011、0.082 g/L,可返回锌冶炼系统配入浸出、净化或送锌电解配液。

| Abstract: | N235 was used to extract zinc and remove fluorine and chlorine from zinc leaching solution.Fluorine and chlorine were extracted into organic phase.Zinc extraction rate is lower than 5%,fluorine extraction rate is over 80%,and chlorine extraction efficiency is over 94%.Organic phase emulsification and long time phase separation can be avoided when isooctanol is added to N235 organic phase,and temperature of extraction,washing and stripping is controlled at 40-45℃.Concentrations of Zn,F,Cl in raffinate is 55.54,0.011 and 0.082 g/L respectively,which can be reused in zinc leaching,purification,and electrolyte preparation. |
