    The present invention relates to a mineral carbonation method and a slag recycling method using reduced slag as a starting material. In the present invention, free lime is removed from the reduced slag by performing pretreatment for reacting free lime surrounding the surface of the reduced slag with carbon dioxide in the atmosphere to form a calcium carbonate thin film on the surface of an aqueous solution. Since the free lime is removed, the solvent extraction efficiency for extracting calcium from the reduced slag by using an ammonium solution can be remarkably improved. Furthermore, the reduced slag can be recycled as building and civil engineering materials by removing the free lime.

    본 발명은 환원슬래그를 출발물질로 하는 광물탄산화 방법 및 슬래그 재활용방법에 관한 것이다. 본 발명에서는 환원슬래그의 표면을 감싸고 있는 유리 석회와 대기중의 이산화탄소를 반응시켜 수용액의 표면에 탄산칼슘막을 형성하는 전처리를 수행함으로써, 환원슬래그로부터 유리 석회를 제거한다. 유리 석회가 제거됨으로써, 암모늄 용액을 이용하여 환원슬래그로부터 칼슘을 추출하는 용매추출효율이 획기적으로 향상될 수 있다. 더 나아가, 유리 석회를 제거함으로써 환원슬래그를 건축 및 토목재료로 재활용 가능하다.
