  • 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

  • Patent number: 9000400
    Abstract: Provided is a portable ultraviolet device for exploring a mineral resource. The portable ultraviolet device for exploring the mineral resource may include a body, a visible component, an ultraviolet lamp assembly, and a darkroom component. The visible component is coupled to the body to pass through the body so that a mineral resource disposed at a lower portion of the body is observed from an upper side of the body. The ultraviolet lamp assembly part is coupled to the body to emit ultraviolet rays onto the mineral resource. The darkroom component is coupled to a bottom surface of the body to surround the visible component and the ultraviolet lamp assembly and defines an external light blocking space having an openable inlet in a lower portion of the body.
