  • Direct Reduced Iron and its Production Processes –

    The reducing agents are carbon monoxide (CO) and hydrogen (H2), coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form. Oxygen (O2) is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metalized DRI.
