| Abstract: |
| Dissolution and reduction of high-iron bauxite by cellulose were carried out. Dissolution and reduction kinetics of high-iron bauxite at different temperatures were analyzed by means of model system. The experimental results show that aluminum dissolution rate and iron reduction rate is 84% and 81% respectively under the optimum conditions include temperature of 280 ℃ and NaOH concentration of 180 g/L. |
