## Direct reduced iron - Wikipedia

Direct reduced iron, also called sponge iron, is produced from the direct reduction of iron ore 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,direct reduced iron handling calculations - BINQ Mining,Direct reduced iron – Wikipedia, the free encyclopedia. Direct-reduced iron has about the same iron content as pig iron, typically 90–94% total ironhandling, and storage.Hot Direct Reduced Iron (HDRI) »More detailedDirect Reduced Iron (DRI) - Cargo Handbook - the world's,,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 higher grades of steel.

Characteristics of reduced iron The MIDREX process produces direct reduced iron (hereinafter referred to as DRI ). The process reduces iron ore using a reforming gas made from natural gas. The DRI is used mainly as the raw material for electric arc furnaces (EAFs), as a clean iron source substitute for scrap iron.
