    OverviewProcessAdvantagesDisadvantages

    The Corex process consists of two main parts a Reduction Shaft and a Melter- Gasifier . The main reagents for the Corex process are iron ore, noncoking coal, and oxygen. Unlike the Blast furnace the Corex process does not use a hot blast of nitrogen, thereby greatly reducing NOx gas emissions, but instead uses oxygen. In addition, the Corex process can use iron oxides containing up to 80% lump ore and uses non coking coal directly as a reducing agent.

  • COREX Process of Iron Making - its Merits and Demerits ...

    In a nutshell, COREX is a coal based SR (smelting reduction) process of making hot metal or pig iron by direct use of non-coking coal. The outputs can be used either by integrated mills or EAF (electric arc furnace) mills. The process gasifies non-coking coal in a smelting reactor, which also produces liquid iron.
