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 Reduced Iron (DRI) - Cargo Handbook
Direct-reduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. The reducing gas is a mixture majority of hydrogen (H2) and carbon monoxide (CO) which acts as reducing agent. This process of directly reducing the iron ore in solid form by reducing gases is called ...
What is the difference between BF pellets and DR …
Theres as such no difference in BF & DR pellets but generally the requirement of pellets in a DR plant is of a higher quality. The cold crushing strength(CCS) of pellets for use in DR is usually greater than 230(to confirm!). I will get into the whys and the supporting documents later.
Heat Transfer in a Bed of Dry Iron Ore Pellets
Iron ore pellets are used as an intermediate product in the production of steel. Their size of approximately 10 mm diameter combines ease of handling with the ability to control air flow and heat distribution in a blast furnace. Previous studies have investigated the thermal properties of iron ore pellets over from 30 to 800°C, i.e. over a temperature range relevant for blast furnaces. 1) It ...

Iron Ore Pelletizing Process: An Overview | …
Iron ore and iron ore pellets are important sources of iron for manufacturing steel. The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries, such as China and India. However, the content of iron ore in deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the enrichment by separation ...
Iron ore pellets – IspatGuru
Iron ore pellets. Iron ore pellet is a type of agglomerated iron ore fines which has better tumbler index when compared with that of parent iron ore and can be used as a substitute of lump ore for the production of direct reduced iron (DRI) and in blast furnaces for the production of hot metal. The term iron ore pellets refers to the thermally agglomerated substance formed by heating a ...
