Zusammenfassung:	The present invention provides an improved process for desulfurization of molten pig iron by a first step of adding powdered aluminum to the molten pig iron and a second step of adding CaO to the molten pig iron, the improvement comprising adding the aluminum as a powdery mixture with CaO, alumina or both, whereby splashing associated with the addition of aluminum alone is reduced.
