Direct reduced iron
In direct reduction the ore is heated to temperatures below its melting point. Direct energy requirements per net ton of direct reduced iron are in the order of 10,000 MJ. The product is 90 to 95% metallized and hence is suitable as a charge in blast, basic oxygen, and electric arc furnaces.

When iron ore is directly reduced from "pellets" or natural lump ore, which has been crushed to a small size, for example, two inches or less in diameter, it has a low degree of density because it is full of cavities where the oxygen has "exited" from sponge iron pellets and after direct reduction, it remains porous and lightweight.

Reduction of iron. In blast furnace, iron is not directly reduced from high valence oxide, but through a process of reduction from high valence oxide to low valence oxide, and then from low valence oxide to iron: Fe2O3 → Fe3O4 → FeO → Fe. The reduction of iron mainly depends on carbon monoxide gas and solid carbon as reducing agent.

Direct Reduced Iron (dri) Direct reduced iron has about the same iron content as Pig Iron, typically 90–94 total iron (depending on the quality of the raw ore) as opposed to about 93 for molten pig iron, so it is an excellent feedstock for the electric furnaces used by mini mills, allowing them to use lower grades of scrap for the rest of the charge or to produce.
