摘　　要：以从钛白废酸中提取的粗钪(Sc2O399%～99.95%)为原料,采用酸溶解、T204和D305多级萃取、反萃以及草酸沉淀等提纯工序,得到的草酸钪经煅烧后可以获得回收率93.49%、纯度99.999%的高纯氧化钪。With crude scandium （Sc203 99%-99.95%） extracted from titanium white waste acid as raw material, scandium oxalate was prepared with the following purification processes including acid dissolu-tion, T204 and D305 multistage extraction and back extraction, oxalic acid precipitation. The results show that scandium oxide with a high purity of 999% is obtained with the recovery of 93.49% after scandium oxalate calcining.
