【摘要】 用Ｘ射线衍射及化学分析法对氯化烟尘中钪浸出条件进行了较系统的实验研究．结果表明：采用１１３ｍｏｌ／Ｌ盐酸水溶液为浸出介质，在Ｓ∶Ｌ＝１∶２，室温条件下浸出钪，钪的浸出率可达８２％以上．更多还原

【Abstract】 Scandium is concentrated in the dust during TiO2 chlorization. The dust can be used as a raw material from which Sc is extracted. In the present article,Sc leaching conditions and leaching media is investigated with X ray diffraction and chemical analysis. The results show that 113mol/L hydrochloric acid solution can be used as the leaching media and the leaching effcient is up to 82% at the ambient temperature and S∶L=1∶2.更多还原
