    Emission Optimized Sintering (EOS ) for lower costs Iron ore sintering creates substantial off-gas volumes, and treating these in order to meet increasingly stringent environmental standards is expensive. EOS uses recycling technology to reduce off-gas volumes by 40 to 50 , resulting in smaller secondary gas treatment systems. This means.The iron ore sintering process is the largest source of emissions of dust and gas pollution in the iron and steel industry. Hematite ores, magnetite concentrates, admixtures (dolomite, limestone and burnt lime), fuels (coke breeze, anthracite) and by-products are used in Poland to produce the sinter mixture.

    Feb 27, 2008 It distinguishes itself from the blast furnace route by (i) Direct use of non-coking coal as reducing agent and energy source and (ii) Iron ore can be directly and feasibly charged to the process in form of lump ore, pellets and sinter. In this technology, iron ore (lump ore, pellets, sinter or a mixture thereof) are charged into a reduction.Silico-ferrite of calcium and aluminum (SFCA) is one of the most commonly-produced phases in fluxed iron-ore sintering, and has long been regarded as an important bonding phase in industrial sinters. It is thus considered to have a significant effect on sinter quality. In this study, a solid solution model and database has been developed for the SFCA phase, and has been incorporated into the.
