| 中文摘要 | Recovery of alkali (sodium salt mainly) from red mud by direct carbonation in CO2 water solutions under different conditions was studied. The process was based on the reaction of alkali with CO2-water solutions to convert the alkali in red mud to more soluble sodium bicarbonate. The carbonation experiments were carried out in a three-phase mechanically agitated slurry-bed reactor. The influence of parameters, such as reaction temperature, reaction time, liquid/solid ratio and CO2 flow-rate, on the alkali recovery rate was investigated. The optimal reaction conditions are as follows: reaction temperature is 60 degrees C, reaction time is 1.5 h, liquid/solid ratio is 10, CO2 flow velocity is 0.8 L/min. |
