The effects of the type of precipitant, the amount of precipitant, the pH value of the leaching solution, the reaction time, the precipitation temperature and the static time on the loss of silicon and vanadium were investigated. The results show that under the condition of weak alkali, aluminum salt has good effect on removing silicon from vanadium containing liquid, and the loss rate of vanadium is less than 1.21% except 99.12% of silicon. The process is simple, and the separation effect of vanadium and silicon is good.Keywords: Vanadium containing leaching solution Magnesium salt Desilication目 录摘 要...................................................................IAbstract................................................................II第一章 绪 论............................................................11.1 引言...............................................................11.2 金属钒简介.........................................................11.2.1 金属钒的历史与资源分布....................................11.2.2 金属钒的物化性质..........................................21.2.3 金属钒的反应及其化合物....................................31.2.4 金属钒的应用领域..........................................31.2.5 金属钒的的危害与防护......................................41.2 钒浸出液除硅的研究内容.......................................
