실험 절차

The calcium oxide powder is digested by water at liquid to solid ratio of 2.5:1 (calculated by the weight of water and calcium oxide) for 60 mins at 80° C. to get calcium hydroxide slurry, and then brine is added by Ca/Mg molar ratio of 1.2:1 for a 60 minutes reaction at 25° C. to get magnesium hydroxide slurry which is then filtered to get magnesium hydroxide cake. The magnesium hydroxide cake is mixed with water at liquid to solid ratio of 50:1 (calculated by the weight of water and magnesia), and then carbon dioxide gas is introduced into it to carbonize continuously at 20° C. Aqueous solution of magnesium bicarbonate (MgO: 18.6 g/L, Fe: 1.7 ppm, Al: 0.3 ppm) is obtained after filtration.
