| 摘 要： | 根据软锰矿和闪锌矿在酸性条件下同槽浸出所得浸出液特点(含铟、锌、锰离子),用P507萃取浸出液中的铟,分离出锌和锰。考察了平衡水相酸度(氢离子浓度)、萃取剂体积分数、萃取温度、有机相与水相体积比、萃取时间等因素对铟萃取率的影响。研究结果表明:在室温下,在平衡水相酸度为2.5 mol/L、P507体积分数为30%(30%P507+70%磺化煤油)、有机相与水相体积比为1∶1、萃取时间为10 min条件下,铟的一级萃取率在99%以上,锌和锰一级萃取率在1.20%以下,铟与锌和锰的分离达到最佳效果;负载有机相经水洗,锌和锰洗涤率为99%,铟洗涤率为0;用2.0 mol/L盐酸进行反萃,铟反萃率在98%以上,达到了富集铟分离锌和锰的目的。

| Abstract: | According to the characteristics(containing indium,zinc,and manganese ions) of lixivium of simultaneously leaching pyrolusite and sphalerite in acidic conditions,indium was extracted and zinc and manganese were separated by P507 from lixivium.Influences of the factors,such as acidity(hydrogen ion concentration) of aqueous equilibrium phase,volume fraction of extractant,extraction temperature,volume ratio of organic phase to water phase,and extraction time on extractive efficiency of indium were investigated... |
