A method for melting DRI consisting at least partly of HBI and/or HCI using a melting process, wherein the HBI and/or the HCI is comminuted before being supplied to the melting process, and HBI or HCI fragments obtained during the comminuting process are supplied to the melting process.

A method for introducing carbon into direct reduced iron (DRI), wherein at least one solid carbon carrier is added to the DRI, and the DRI is hardened once the solid carbon carrier has been added to the DRI.

A method of introducing a metalliferous feed in an ironmaking process, the method including 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, wherein the metalliferous feed is subsequently injected into a cyclone part of a metallurgical vessel.
