  • COREX IRON MAKING PROCESS PDF - Brandi Belle

    In Siemens first completed a life cycle assessment for pig iron production, looking at both conventional production in a blast furnace and the more environmentally friendly COREX and FINEX processes. Iron ore lump ore, pellets, or a mixture thereof is charged into the reduction shaft, where it is reduced to direct reduced iron DRI by the reduction gas in counter flow.
