Direct reduced iron process - tec-science
The reduction gases only dissolve oxygen from the iron ores. This causes the iron ores to crack on the surface. The appearance resembles a porous sponge, which is why the deoxidized and thus strongly ferrous iron ore is also called sponge iron. Sponge iron is a highly ferrous ore from the direct reduced iron process!

Direct Reduction of Iron Ore with Green Hydrogen
Direct reduction of iron ore refers to the conversion of solid iron ore to metallic iron without conversion to the liquid phase . Majority of the direct reduced iron (DRI)  is produced by reacting iron oxide with hydrocarbon-based reducing gases produced from reforming natural gas or coal gasiﬁcation [39–42].

dri prices india fob direct reduced iron dollars tonne
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 carbon produced from natural gas or coal. Its main use is as raw material feedstock for electric furnaces in mini mills, where DRI can be used as a scrap substitute.

Direct Reduced Iron (DRI) Production Plant
Direct Reduced Iron (DRI) Production Plant NIPPON STEEL ENGINEERING CO., LTD. Basic Concept or Summary S-16 u A direct reduced iron (DRI) production plant is a shaft reduction furnace to produce DRI with large metal iron content by directly reducing iron ore (or iron ore pellets) with reducing gases.
MIDREX® Process - Midrex Technologies, Inc
As the iron ore descends through the furnace by gravity flow, it is heated, and the oxygen is removed from the iron ore (reduction) by counterflowing gases that have a high H₂ and CO content. These gases react with the iron oxide in the iron ore and convert it to metallic iron, leaving H ₂ O and CO ₂ .
