    To stabilize a steel slag by a treatment different from conventional aging treatments.SOLUTION: The Ca component of steel slag is extracted into a solvent by conducting a contact treatment in which the steel slag is brought into contact with the solvent. When at least one of the estimated f-CaO content and free CaO content in the steel slag exceeds a threshold value, it is preferable to further conduct an aging treatment on the steel slag that has already undergone the contact treatment.SELECTED DRAWING: None

    【課題】従来のエージング処理とは異なる処理によって製鋼スラグを安定化させる。【解決手段】製鋼スラグに、溶剤と接触させる接触処理を施すことにより、上記製鋼スラグのＣａ成分を上記溶剤に抽出する。上記製鋼スラグの推定ｆ－ＣａＯ量および遊離ＣａＯ含有量の少なくとも一方が閾値を超える場合に、上記接触処理を施した上記製鋼スラグに、エージング処理を更に施すことが好ましい。【選択図】なし
