Description. Iron Ore (fines) Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH).n(H 2 O)) or siderite (FeCO 3).

May 14, 2015· Brazilian Blend fines, or BRBF, which will have typical iron content of 63.1%, will be a blended product of Iron Ore Carajas fines from the northern system and high silica ores from the southern system, said Cecilia Silva, Vale's Commercial Marketing General Manager, Iron Ore, at a major iron ore conference in Singapore Thursday.

Sintering is agglomeration of fine grained iron ore for blast furnace burden preparation. During the sinter transportation process fine sinter (–5 mm) is produced which cannot be charged in the blast furnace as high percentage of fines creates gas flow problem in blast furnace. The screened sinter is recycled to the raw material bedding and blending plant.

Abstract Iron ore sinter, constituting a major proportion of blast furnace burden, significantly impacts the blast furnace performance. The chemical composition of iron ore fines, particularly alumina, sinter basicity and sinter MgO together with the thermal conditions that sinter blends are subjected to play an important role in the formation of mineral phases in sinter.

ore fines the mean size of the iron ore fines will change. With decreasing the coarser size fraction increases the finer size fraction in iron ore fines. 2.2. Sintering For each individual iron ore fines of different mean sizes, pot grate sinter experiments were carried out by preparing the granules in lab scale granulation drum. The raw material

Low-temperature (< 1300 °C) iron ore sinter is an agglomerate of unmelted and partially melted nuclei particles (+ 1 mm) and a matrix bonding phase produced from the melting of fine ore (− 1 mm) and flux particles, with the majority of melt formation occurring in the granule adhering fines layer. The majority of nuclei are hematitic, but ...

iron ore processing and sintering plant. Iron Ore Sintering Process Sinter plants agglomerate iron ore fines dust with other fine materials at high temperature to create a product that can be used in a blast final product a sinter is a small irregular nodule of iron mixed with small amounts of other minerals.

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 …

Iron ore fines are the main source for sinter making. To improve the sinter properties it is necessary to provide good quality of iron ore fines. Due to depletion of high grade iron ore resources, goethite and limonitic ore content in iron ore fines is expected to increase gradually.
