Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method of treating a steel slag, which prevents fluorine, COD component, and calcium from being eluted from a treated steel slag and simultaneously reduces pH of an eluent.SOLUTION: The method of treating the steel slag includes: mixing the steel slag with a predetermined amount of water and then kneading the resultant mixture; and subjecting the kneaded product to hydrothermal curing treatment, thereby preventing the fluorine, the COD component, and the calcium from being eluted from the treated steel slag and thereby simultaneously lowering the pH of an eluent.
