| 摘 要： | 赤泥是铝工业生产过程中的废弃物,其中含有有价值的金属钪,通过盐酸浸出、有机溶剂萃取可实现钪的富集分离。当选用w(P204)为1%和w(TBP)为1%的萃取剂、1∶1的V(O)∶V(A)(O为有机相,A为水相)时,在3 mol/L的酸度下进行10 min振荡萃取后,钪的提取率可达到90%以上,铁的提取率只有3.6%,钪与铁的分离系数为312,为后续钪的进一步提取提供了有力的条件。

| Abstract: | Red mud is polluted waste in the course of production of aluminium,containing valuable metallic Scandium. By hydrochloric acid leaching, solvent extraction can realize the enrichment and separation of scandium. When the mass fraction of P204 and TBP is 1%, the O/A ratio is 1：1,the acidity is 3mol/L, the oscillation time is 10min,the extracting rate of Scandium is more than 90% ,and the extracting rate of Fe is 3.6%.The separation coefficient of Sc and Fe is 312,providing a good conditions for subsequent scandium extraction. |
