Procedure

The second method of preparation of the aqueous solution of magnesium bicarbonate in technical solution is to add water to magnesium oxide to digest at 50˜95° C. for 0.5˜5 hours, with the weight ratio of the liquid to solid: 1˜5:1 (calculated by the weight of water and magnesium oxide). Water is added to form slurry or magnesium hydroxide and water is mixed directly based on the weight ratio of the liquid to solid: 10˜200:1 (calculated by weight of water and magnesium oxide and/or calcium oxide). Then the slurry is carbonized by carbon dioxide gas, with reaction temperature controlled at 0˜50° C. and reaction time 0.1˜5 hour. Pure aqueous solution of magnesium bicarbonate is obtained by filtration.
