. Sulfuric acid (98%), hydrochloric acid (36%), thiourea, sodium chloride, ferric sulphate, and sodium lignin sulfonate used in these experiments are all chemically pure, and 260# kerosene, Acorga M5640.... After the lixivium was neutralized, the copper was extracted with Acorga M5640. Volume ratio of extractant to 260# kerosene was 1:4, and the process of eleven-stage countercurrent extraction, one......
medium using Lix series extractants have been reported[2-15]. Now, Lix 984N and M5640 are widely used as extractive reagents. Lix 984N is a mixture of Lix 860N and Lix 84 in kerosene. The active......

年钴的消费水平大幅增长,总量仅次于美国和日本,而且我国铜消费量也在逐年增长,因此加强铜和钴二次资源的综合回收利用有着重要意义[1-6].由于湿法冶金技术的进步,陆续发明了很多铜的高效萃取剂,如Lix54,Lix63,Lix84,Lix973,Lix984,N902和M5640等,有的获得了工业化应用.在氨性水溶液体系中,能够实现铜钴分离的萃取剂的种类较少.目前比较常用的是科宁公司的 Lix 系列产......
~5.0之间可使Al3+的去除率超过98%[86].去除浸出液中Cu2+的主要方法有萃取除铜[87],Fe粉置换除铜[88]以及Na2S2O4除铜[89]等.萃取铜常用的萃取剂为M5640,李学鹏等[87]利用M5640从含有Ni2+和Co2+等离子的溶液中萃取除铜,在最佳条件即pH=3,相比为1:1,萃取剂体积分数为15%,震荡时间为5 min下,铜离子的萃取率高于99.8%.萃取除铜具有产品纯度... processes 3.2.2 溶剂萃取法 溶剂萃取法是另一种常用的从溶液中分离金属离子的方法,其原理是利用化合物在2种不同液体中的溶解度不同而实现各自分离.尽管采用此法分离具有相似萃取性能离子的效率较低,但此法仍然是一种高效可行的方法,已有多种萃取剂如Cyanex 272,D2EHPA,Acorga M5640,三辛胺(TOA)和PC-88A等用于从废旧锂离子电池浸出液中分离回收Ni,Co和......
