Study on Dissolution Behavior of High Titanium Bauxite

摘要

Dissolution behavior of high titanium bauxite was investigated. The effect of several factors on dissolution of alumina and titanium dioxide were examined. The experimental results showed that the titanium dioxide dissolution rate was 9.82% and alumina relative dissolution rate was 88.83% under the best dissolution conditions for dissolution temperature of 240°C, lime add volume of 4%, and alkali concentration of 220g/L.
