Sponge iron, also called Direct-reduced iron (DRI),[2] 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 (H 2) and carbon monoxide (CO) which acts as reducing agent.

Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BF-BOF and Scrap-EAF routes. In DRI, iron ore is reduced in its solid state – unlike BF process where a liquid metal is formed during reduction. DRI can then be transformed to steel in electric arc furnaces. DRI production is common in Middle East, South America, India and Mexico.

The Direct Reduction of Iron - ScienceDirect
In contrast to iron oxide reduction in a BF, direct reduction occurs in the solid state, and none of the components are melted. While this is good from an energy perspective, there is little or no way to remove impurities from the system, which are then carried with the direct reduced iron (DRI) product to the steelmaking furnace.
