OPTIMIZED MELTING OF COMPACTED DRI
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.
FLUIDIZED BED IRONMAKING PROCESS AND SYSTEM
In various examples, the subject matter of this disclosure relates to a method and a system for producing metallic iron. An example method includes: obtaining bio-oil; obtaining iron ore fines; providing the bio-oil to a gasifier to produce syngas from the bio-oil, the syngas including tar and/or particulate; and providing the syngas and the iron ore fines to a fluidized bed reactor where iron oxide in the iron ore fines is at least partially reduced using the syngas.

Method of introducing a metalliferous feed in an ironmaking process
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.
