.尹中林[71]采用盐酸浸出赤泥的方法,P204+仲辛醇+煤油做萃取剂从浸出液中萃取钪,经除杂反萃后得到氢氧化物沉淀,盐酸溶解,TBP+仲辛醇+煤油萃取钪,使其富集,反萃后加酒石酸和氨水,灼烧沉淀,最终得到92.25%的Sc2O3.张江娟等[72]探索了从赤泥的盐酸浸出液中回收钪的工艺条件:以1%P507+煤油为有机相,相比O/A=1:1,萃取时间15 min,钪的萃取率达90%以上;用6 mol... WANG等[74]研究了用硫酸,盐酸,硝酸处理赤泥后各元素的浸出率,发现稀硫酸对钪的浸取效果较好,还研究了3种有机磷萃取剂对提钪的影响,发现D2EHPA表现最好,将TBP作为相调节剂可改善分离效果.此外,研究不同pH条件下钪与铁,锆,钛的分离系数,最后提出了从赤泥硫酸浸出液中提钪工艺,如图6.在低pH下使用低浓度的PrimeneJMT将锆,钛除去,纯化后的浸出液用D2EHPA/TBP体系萃取钪,酸......
