  • Methods of producing carbonate minerals and apparatuses of producing the carbonate minerals
    Patent number: 9174184
    Abstract: An apparatus of producing a carbonate mineral includes 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 an alkaline earth metal ion from the first reaction device; and a carbon dioxide supplying device supplying a carbon dioxide to the second aqueous solution.
    Type: Grant
    Filed: February 4, 2014
    Date of Patent: November 3, 2015
    Assignee: KOREA INSTITUTE OF GEOSCIENCE AND MINERAL RESOURCES
