Advantages of recent developments in iron ore sintering

iron ore pelletizing process an overview intechopenjul , · the iron ore production has significantly expanded in recent s, owing to increasing steel demands in developing countries. however, the content of iron in ore deposits has deteriorated and lowgrade iron ore has been processed. the fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. this chapter shows the status of the pelletizingiron ore sintering process in steel manufacturingsinter is the primary feed material for making iron in a blast furnace. sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control the chemistry and then igniting it at 10°c in a continuous beltfed furnace.the sintering process of iron ore fines ispatgurumar 09, · sintering is a thermal process (carried out at 00 deg c to 00 deg c) by which a mixture of iron ore, return fines, recycled products of the steel plant industry (such as mill scale, blast furnace dusts, etc.), slag forming elements, fluxes and coke fines are agglomerated in a sinter plant with the purpose of manufacturing a sintered product of a suitable chemical composition, quality (physical)minerals special issue mineralogy of iron ore sintersmay , · iron ore sintering is an important stage in the production of steel from iron ore. sinter can constitute more than 60% of ferrous burden in modern blast furnaces in japan and most blast furnaces in europe. iron ore sintering is a high temperature process which converts iron ore fines (<68 mm in size, too small for direct feed into the blastemission reduction research and development of pcdd/fs injul 01, · iron ore sintering process is the second to the municipal waste incinerator toxic pollutants emission source and more than 50% of dioxin emissions are from sintering process in the iron and steel industry (cang et al., ;
