Direct-reduced iron (DRI), also called sponge iron is produced from direct reduction of iron (in the form of lump, pellets or fines) by a reducing gases produced from natural gas or coal. This reduction takes place in the temperature range 800- 1050 degrees C when reducing gases; mainly Hydrogen and Carbon-monoxide; react with the iron oxides to produce iron.
Sponge Iron – Prakash Industries Limited
Sponge iron is a highly processed form of iron ore which contains metallic iron in the range of 83-88% obtained by direct reduction without melting it. Due to high porosity, the resulting iron is called sponge iron. It is used as a raw material for manufacturing steel

The Ironmaking Process | New Zealand Steel
The success of this direct reduction process of ironsands on a commercial scale was a hard-fought technological battle, culminating in a world first achievement for New Zealand Steel. At the Waikato North Head mine, the ironsand is concentrated by magnetic and gravity separation processes to increase the iron content and decrease the amount of loose impurities.

Iron ore raw materials (IORMs) are Fe-containing minerals prepared for further processing into iron, direct reduction iron (DRI) and ferroalloys. IORMs come from iron ore, a rock containing Fe in such quantities that it is advantageous to process the ore. Iron Ore
Blast furnace process - tec-science
In the indirect reduction zone, the iron oxide contained in the iron ores is reduced by carbon monoxide gas, whereby the iron ores are not melted! Direct reduction zone If the iron ores, which have not yet been reduced, move further down in the blast furnace, then the carbon can also directly reduce the iron oxides contained in the ore due to the high temperatures.
Recycling direct-reduced iron produced by rotary hearth furnace in the blast furnace has the effect of reducing the reducing agents consumption, such as coke. The zinc removed within the rotary hearth furnace can also be recovered as crude zinc oxide at a waste gas processing facility, allowing it to be sold as a high-grade raw material for zinc refining.
First in fossil-free steel - SSAB
SSAB is taking the lead in decarbonizing the steel industry. With HYBRIT technology, SSAB aims to be the first steel company in the world to bring fossil-free steel to the market already in 2026. SSAB will be practically fossil free by 2045.
The FINEX Process :: Total Materia Article
In the Finex process, iron ore fines are charged into a series of fluidized-bed reactors. The fines pass in a downward direction where they are heated and reduced to direct-reduced iron (DRI) by means of a reduction gas – derived from the gasifiion of the coal
