Direct reduced iron   </h3>OVERVIEWPROCESSHISTORYCHEMISTRYUSESDirect 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. Reduced iron derives its name from the chemical change that iron ore undergoes when it is heated in a furnace at a high temperature of 800 to 1200 C in the presence of a reducing gas called syngas which is a mixture of hydrogen and carbon monoxide. Direct reduction
