In iron and steel industries, fine iron ore usually needs to agglomerate to form iron ore sinter through high-temperature sintering process and then fed to the blast furnace.In iron ore sintering process, raw materials, including iron ores, fluxes, fuel, and return fines, are blended uniformly and subsequently granulated in a tumbling.

Ultra fines iron ore in sinter production.Recovery improvement of fine iron ore particles by bentham open.Apr 9, 2009 ore producing countries have increased their production by initiating steps to high alumina in iron ore and sinter leads to viscous slag formation during.Ultrafines like tin, chromium, iron and other ore.
The sintering process of iron ore fines ispatguru.Mar 09, 2013 sintering is a thermal process carried out at 1300 deg c to 1400 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.
The smaller sized iron ore fines 100 mesh shall reduce the permeability of sinter bed and this in turn will generate more sinter return-fines and thus productivity of sinter machine is affected.So the ideal size distribution of iron ore fines must be 10 to 0.15 mm and mean size of the ore fines.
