Direct reduced iron Wikipedia

Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting

Briquetting of Fine‐Grained Residues from Iron and Steel

4 Briquetting with a Binder. Cold bond briquetting may offer a method for recycling the residues. Fines, dusts, and sludge can be briquetted using a binder to a form that is suitable for charging into the Midrex shaft. To get briquettes with sufficient mechanical strength and thermal stability, a binder is needed.

Cold Briquetting of DRI Fines for Use in Steel Making Process

DRI fines, generated during its manufacture and handling, generate high content of fines in the size fraction less than 2 mm. It has iron content above 80%. It is difficult to directly use such iron-rich material in the primary steel making process, without agglomeration. At JSW Steel Vijayanagar, around 50 to 70 tons per day of DRI fines with < 2 mm size fraction get generated.
