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.

IRON ORE / TACONITE SHIPPING All of the iron ore that is mined in the UP of Michigan and in northern Minnesota is moved out of the region as taconite pellets. Most of that moves via train cars and then via large ore freighters, such as the one shown below. Rail transport of taconite takes place from the Marquette range area (where it is mined) to either Escanaba or …

Direct Reduced Iron (DRI) DRI is the raw material for the electric arc process of steel production, which is the primary method of steel production in the world (having superseded the blast furnace process in most countries). DRI is made by passing reducing gases over iron ore, usually in the form of pumps or pellets.
