Lower Environmental Impact• Recycle Wastes– Utilise iron ore slimes– Steel plant wastes– Other iron unit sources (e.g. steel-making slag)• No Toxic Emissions– No dioxins, furans, phenols or tars• Reduced Overall Emissions– Reduced CO 2, SO 2and NO x– CO 2Emissions• Now in line with BF• Future plants (Circofer) reduced emissions• Circofer CO 2 can be sequestered• Low Footprint– Less land disturbance– Power balancedSource: Rio Tinto analysisEmissions per thm2.52.01.51.00.50.0Best-in-class BFHIsmeltCO2 SOx NOx Dioxines &Furanes*(t/thm) (kg/thm) (kg/thm) (ppm/thm)© HIsmelt Corporation 2008Higher Quality Iron: Compared to blast furnacesTypical AnalysisCarbonSiliconManganesePhosphorusSulphurTemperatureBlast Furnace4.5%0.5 ± 0.3%0.4 ± 0.2%0.09 ± 0.02% *0.04 ± 0.02%1430 - 1500°C4.4 ± 0.15%
