The moisture content of iron ore fluxed pellets was calculated proportionally according to the amount of water required by pure iron ore and pure limestone pellets (135% and 165% respectively) Therefore, a fluxed charge containing 10% limestone needs 138% water and a charge containing 20% limestone needs 141% water content
Jun 13, 2014· BF burden, blast furnace, Hot metal, Iron ore, iron ore pellets, sinter, Use of Iron Ore Pellets in Blast Furnace Burden Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 8-20 mm in diameter by a .
Iron ore pelletizing systems Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets These are typically fed to a blast furnace or DRI plant as part of the process to make steel
A new fluxed pellet for use in iron-making is obtained by mixing and indurating about 1 to about 20%, by weight of the pellet, of ground melt shop slag fines with similarly ground iron ore concentrate, so as to achieve particular ranges of silica content, CaO/SiO 2 ratio, and MgO content The melt shop slag fines have been considered a waste material, but contain significant slag and metal valu

Iron ore and iron ore pellets are important sources of iron for manufacturing steel The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries, such as China and India However, the content of iron ore in deposits has deteriorated and low-grade iron ore has been processed
Iron ore concentrates must be coarser than about No 10 mesh to be acceptable as blast furnace feed without further treatment Finer concentrates are agglomerated into small "green" pellets, which are classified as either acid pellets or flux pellets Acid pellets are produced from iron ore and a binder only, and flux pellets are produced by
Standard pellets require less processing, are generally the least costly pellets to produce and are called “standard” because no ground fluxstone, such as limestone or dolomite, is added to the iron ore concentrate before turning the concentrate into pellets In the case of fluxed pellets, fluxstone is added to the concentrate, which .
