| 摘 要： | 本研究旨在从攀枝花选钛尾矿中提取钪。先将选钛尾矿分选成含钪１２１ｇ／ｔ的钪精矿，再经盐酸浸出，作为提钪原料。采用ＴＢＰ萃取钪，钪的萃取率为９８．９％；用氢氧化钠反萃，反萃率为９７．９０％；对萃取液或反萃液采用氢氧化钠、草酸盐精制，得到了９９．９６％的Ｓｃ２Ｏ３产品。

| Abstract: | This research is to extract Sc from tails of separating Ti in Panzhihua.First,tails are separated and concentrate is obtained which contains 121g/t Sc.Concentrate is extracted by hydrochloric acid immersior to get Sc using TBP,and the extraction ratio is 98.9%.Then sodium hydroxide counterextraction is carried out.The counterextraction ratio is 97.9%.Extraction or conuterextraction solution is refined by using sodium hydoxide and ammonium salt.The product of 99.96% Sc2O3 is obtained. |
