Reduction of Iron Ore Pellets, Sinter, and Lump Ore

2020-3-23  It was seen that in lower temperatures and the gas composition tied to those, iron ore pellets are the fastest to reduce, whereas sinter and lump ore follow behind. In higher temperatures, sinter bypasses the iron ore pellets, and lump ore stays the last in all cases.

SINTERING AND PELLETISATION OF INDIAN IRON ORES

2020-2-2  Emission Optimized Sintering (EOS®) for lower costs Iron ore sintering creates substantial off-gas volumes, and treating these in order to meet increasingly stringent environmental standards is expensive. EOS® uses recycling technology to reduce off-gas volumes by 40 to 50 %, resulting in smaller secondary gas treatment systems. This means:

Ore Sintering - an overview ScienceDirect Topics

2010-4-2  This allows the sintering of the iron ore granules on the grate to move downward with the flame front, while the grate proceeds horizontally toward the discharge point of the strand. The sinter strand speed and gas flow are so controlled that “burn through” (i.e., the point at which the flame front reaches the base of the strand) occurs just prior to the hot sinter being discharged.

Solid state sintering in the induration of iron ore pellets

Data is developed to show the relationship between pellet strength and shrinkage which accompanies induration. Systematic measurements of shrinkage kinetics of a pure hematite reagent powder and of a commercial magnetite concentrate are presented, and rate constants and activation energies evaluated. The discussion links the results of pellet induration research with sintering theory ...
