Abstract
A method of manufacturing iron in a metallurgical vessel, the vessel including a bath of molten iron with on top of the bath of molten iron a layer of slag, wherein a metalliferrous feed, carbon containing material, fluxing material, and oxygen or an oxygen-containing gas are introduced into the vessel to convert the metalliferrous feed into molten iron that is collected in the bath of molten iron and continuously or semi-continuously tapped from the vessel through an iron—outlet of the vessel, and wherein the composition of the fluxing material is selected to acquire a predetermined slag chemistry, which slag is regularly tapped out of the vessel through a slag—outlet, and the fluxing material includes slag derived from a steelmaking process.
