Procedure

Magnesium oxide is hydrated for 0.5 hours at 95° C. The weight ratio of water to magnesium oxide is 2:1. Then water is added into the mixture to prepare slurry at a weight ratio of water to magnesium oxide of 50:1. After that, carbon dioxide (85 vt %) is introduced into the slurry to react for 3.5 hours at 18° C. Subsequently, a pure magnesium bicarbonate solution (MgO: 17.2 g/L, Fe: 3.5 ppm, Al: 2.2 ppm) is obtained after clarification and filtration.
