盐酸体系N503萃取分离回收铟
Indium Recovery by Extraction with N503 from Hydrochloric Acid System
【摘要】 真空炉锗渣经加钙盐氯化蒸馏提锗后,金属铟及铁、锡、锑等一同进入蒸馏残液中,以此残液为原料,N503为萃取剂,考察了不同萃取条件下残液中各金属离子的走向。结果表明,该工艺适合相对低酸度条件,而且铟萃取率高,并可回收三氯化铁、锡和锑,萃取剂可再生循环使用。
【Abstract】 In,Fe,Sn and Sb entered into the vinasse liquid in the process of germanium extraction from chloridization-distilling slag with calcium salt addition.Indium was extracted successfully with N503 from this lixiviated liquid,and the trends of mostly metal ion under different extracting condition were investigated.The results show that extraction process is fit of low acidity,indium extraction rate is higher,FeCl3,Sn,Sb could be recovered and the extractant could be reused after regeneration.
