Abstract
LD slag, that is, a by-product of steel making process, has been mainly used as land construction materials. Recently, the seashore application of LD slag was tried in Japan and Korea but the reaction between LD slag and seawater was not studied yet. We tried to clarify the leaching reaction and/or mechanism of LD slag and the reaction between seawater and LD slag. We tried to apply these results to the decarbonization of seawater for seawater magnesia process. The high pH solution(over 12) was injected into the sea water and the pH of mixed liquid was adjusted to 9.8. This mixed solution was aged for 8 hours and the 104ppm of CO
