An apparatus of producing a carbonate mineral, comprising:
- a first reaction device including a fluid path along which an ion exchange solution moves;
- a cation exchange medium disposed in the fluid path, the cation exchange medium containing an alkaline earth metal;
- a second reaction device accommodating a sodium hydroxide aqueous solution and receiving the ion exchange solution containing ions of the alkaline earth metal from the first reaction device;
- and
- a carbon dioxide supplying device supplying a carbon dioxide to the sodium hydroxide aqueous solution,
- wherein the ion exchange solution comprises cations exchanged with the ions of the alkaline earth metal, and the ions of the alkaline earth metal react with carbonate ions to form the carbonate minerals within the second reaction device.
