Direct Reduction Process Description | …

Process Description. R&D Trends. In a direct reduction process, lump iron oxide pellets and/or lump iron ore, are reduced (oxygen removed) by a reducing gas, producing direct reduced iron (DRI). If the cooling stage is omitted, the DRI can be immediately briquetted into hot briquetted iron (HBI). The reducing gas can be generated externally to
