| Abstract: |
| The effects of temperature, time, ratio of liquid to solid(L/S), and concentration of sodium carbonate in correction liquor in clinker digestion process were investigated with orthogonal experiment and single factor experiment, and the four factors were determined based on influence momentum. The results show that the four factors in sequence from high to low are temperature, time, L/S, concentration of sodium carbonate. The leaching rate of alumina is 91.26% under the conditions including digestion temperature of 80 ℃, dissolving time of 30 min, L/S of 5∶1, and concentration of sodium carbonate of 20 g/L. |
