Zusammenfassung:An additive for use in the desulfurization of molten iron comprises a granular mixture of metallic magnesium, calcium oxide and a small amount of a hydrocarbon-containing material which provides a volatile gas producing component to the mixture. The volatile content of the additive is between .25 and 5 percent. The hydrocarbon-containing material is preferably coal, carbon black, wood flour or a high density polyethylene. The additive is intended to be pneumatically injected into the melt in a stream of non-oxygenated carrier gas.
