Zusammenfassung:Method of introducing a metalliferous feed (4) in an ironmaking process, the method comprising the steps of, pre-drying an iron containing sludge by drying means to an amount of 15 to 30% (w/w) moisture, mixing the pre-dried iron containing sludge with a binder material to obtain a granulate, having a particle size of less than 4 millimeter and drying the granulate to a maximum of 3% (w/w) moisture, thereby forming the metalliferous feed (4), characterised in that the metalliferous feed (4) is subsequently injected into a cyclone part (10) of a metallurgical vessel (1).
