Zusammenfassung:	Embodiments of the present invention are to provide a molten iron desulfurization method capable of easily excluding slag generated at the time of desulfurization. The molten iron desulfurization method comprises: a step of loading molten iron to a desulfurization ladle; a step of inputting quicklime to the molten iron to desulfurize the molten iron; a step of inputting a slag coagulant into the molten iron; and a step of excluding slag floating on an upper layer of molten iron, and coagulated by the slag coagulant. 용선 탈황 방법이 개시된다. 용선을 탈황래들로 장입하는 단계; 상기 용선에 생석회를 투입하여 상기 용선을 탈황하는 단계; 상기 용선 내에 슬래그 응집제를 투입하는 단계; 및 상기 용선 상층에 부유하며, 상기 슬래그 응집제에 의하여 응집된 슬래그를 배재하는 단계를 포함하는 용선 탈황 방법이 제공된다.
