SINTER PLANT The purpose of the sinter plant is to transform raw material fines into a coarse size iron ore sinter, ready to be charged to the blast furnace. Sintering of fine particles into a porous clinker – sinter – is necessary to improve the permeability of the burden, making reduction easier.
· In reflected light microscopy of iron ore and iron ore sinter, each sample (typically one size fraction when studying ore fines) is mixed with liquid epoxy resin and allowed to settle. Large iron ore or sinter pieces are also usually embedded in epoxy, which simplifies the polishing procedure and significantly improves polishing quality.
The chemical analysis of iron ore sinter is given in Table 3. The X-ray diffraction analysis of the applied sinter exhib-ited that the sinter was composed of three main phases: hematite, calcium silicate, and calcium ferrites as given in Fig. 2. The microstructure of
Iron ore sinter is a complex composite material of ~40–70 wt% iron oxides (hematite, Fe 2 O 3, and magnetite, Fe 3 O 4), 20–50 wt% Ca-rich ferrite phases, up to 10 wt% glasses, and up to 10 wt% calcium silicates of which larnite, Ca 2 SiO 4, is the most 2001).
This also pertains to iron sinter, which is constituted of a mixture of raw materials, namely iron ore, fluxes, coke breeze, limestone, lime, dolomite, and return sinter fines, all having various size distributions. Currently Mittal Vanderbijlpark uses
· Sintering: A Step Between Mining Iron Ore and Steelmaking. The USGS defines iron ore as a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). It''s a major ingredient in steel.

· The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade 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 pelletizing process ...
· In hybrid pellet sintering process, iron ore concentrate of relatively finer size is first converted into micro-pellets and these micro-pellets are used in place of iron ore fines. The prerequisite for micro-pellets to be used in hybrid sintering is to have sufficient green strength so that they does not get disintegrated during mixing with other raw materials and during charging on the sinter ...
