Method of manufacturing iron in a metallurgical vessel

A method of manufacturing iron in a metallurgical vessel, said vessel comprising a bath of molten iron with a layer of slag on top of the bath of molten iron,

• wherein a metalliferrous feed, carbon containing material, fluxing material, and oxygen or an oxygen-containing gas are introduced into the vessel during the manufacturing of iron 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, the vessel being provided with a cyclone,
• wherein the fluxing material comprises slag derived from a steelmaking process,
• wherein the particle size of the slag derived from a steelmaking process is less than 3 mm;
• wherein the slag derived from the steelmaking process is not mixed with the metalliferrous feed before introducing into the vessel, and/or
• wherein the slag derived from the steelmaking process is introduced into the vessel via and/or below the cyclone.
