Direct-Reduced Iron an overview ScienceDirect Topics

Jan 05, 2012 Direct reduction (DR): Direct reduction involves the production of solid iron from iron ores and a reducing agent (e.g., natural gas). The solid product is called DRI and is mainly applied as feedstock in EAF. The direct reduction process has been commercialized since the 1970s and a variety of processes have been developed. (2)

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 reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron. Reduced iron derives its name from these processes, one example bein

DRI production International Iron Metallics Association

A cost comparison: Production and smelting of prereduced

The major capital expenditure in a plant to make prereduced pellets is for kilns and coolers. Other items, beyond those required for conventional pellets, such as reductant bins and conveyors, add little to the depreciation charge per ton of product. Prereduced pellet plants cost more per product ton than those for oxide spheres largely because there is more iron in the metallized pellets.
