Procedure

Magnesium hydroxide is diluted by the wastewater generated from Example 9 with pH 5 at liquid to solid ratio of 60:1 (calculated by the weight of water and magnesia). And then carbon dioxide gas (90 vt %) is introduced into it to react for 5 hours at 0° C. Pure aqueous solution of magnesium bicarbonate (MgO: 15.2 g/L, Fe: 0.8 ppm, Al: 1.6 ppm) is obtained after clarification and filtration.
