摘要
Abstract
Removing of Si and Fe from sodium aluminate solution for preparing high purity alumina was studied .The effects of CaO amount ,reaction temperature and reaction time on removal of Si ,Fe and the Al concentration were examined .The results show that Si and Fe can be removed quite completely by adding CaO .The optimum conditions is CaO amount of 8 g /L ,reaction temperature of 80 - 85 ℃and reaction time of 2 h .The removal rate of Si and Fe in the sodium aluminate solution are 98 .52%and 98 .44% ,respectively .And the loss of aluminum can be controlled effectively at the best conditions .关键词
