Versuchsvorschrift

The roasting process of magnesium or/and calcium minerals is that the minerals are roasted for 1˜5 hours at 700˜1000° C. The process of digestion is that water is added into magnesium oxide and/or calcium oxide obtained after roasting to digest at 50˜95° C., for 0.5˜5 hours, according to the weight ratio of the liquid to solid: 1˜5:1 (calculated by the weight of water and magnesium oxide and/or calcium oxide), and then water is added to form slurry 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). The process of carbonization is that the slurry is carbonized by carbon dioxide gas after digestion, with reaction temperature controlled at 0˜50° C. and reaction time 0.1˜5 hours. Pure aqueous solution of magnesium bicarbonate and/or calcium bicarbonate is obtained by filtration.
