The sintering process of iron ore is followed by a great emission of gaseous sulfur compounds into the atmosphere which takes to the human environment pollution. According to certain evaluations, from the total emission of gaseous sulfur compounds in one forge, the emission in the sintering process of the iron ore is from 40% to 60%.


During the iron ore sintering process, two types of particles are present in the sinter bed: (1) fines, which are actively taking part in melting and the formation of secondary phases, and (2) coarse ores, which are partially interacting with the surrounding melt. The quality of the final sinter is particularly determined by the secondary phases and their bonding ability.


A process for sintering an iron ore blend of iron ore particles, the iron ore blend comprises soft/porous ores is disclosed. The process comprises forming a green mix of the iron ore blend and a flux; granulating the green mix with water; and sintering the granulated green mix. The process is characterised by a treatment step to inhibit absorption of water into the soft/porous …


the blast furnace process, to the sintering of iron ore and iron ore pelletizing are the main areas. In this investigation the usefulness of the olivine mined at Greenland for sinter – and pellet production was studied. The chemical analysis of the olivine from Greenland shows an olivine mineral with high fosterite content.


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 manufacturing a sintered product ...
