Iron ores — Determination of total iron content
of iron ores, using potassium dichromate as titrant after reduction of the iron(III) by tin(II) chloride and titanium(III) chloride. The excess reductant is then oxidized by potassium dichromate solution. This method is applicable to total iron contents between a mass fraction of 29,04 % and a mass fraction of 72,02 % in natural iron ores and ...

CHAPTER
iron ore. Fig. 3.3 : Effect of size of ore on degree of reduction. Iron ore and agglomerates as charge material should be resistant to abrasion. If they break into finer fractions due to impact, abrasion, compression and volume change within the furnace, the smaller particles result in choking of voids thereby affecting reduction and productivity.

Reduction of Iron Ore Pellets: A Microstructural Perspective?
Twenty different iron ore pellets, consisting primarily of Hematite (Fe2O3) phase, were subjected to 'simulated' reduction studies. A wide range of reduction time periods, Rt of 122 to 211 minutes, were obtained. Detailed microstructural characterizations were then conducted at different locations of ten selected specimens. The Rt did not …

Iron ores — Determination of loss on ignition — Gravimetric …
The measurement of loss on ignition (LOI) is a technique widely used in the iron ore industry. Ignition loss is the sum of contributions from the mass loss of volatile compounds water vapour, carbon dioxide and sulfides (due to the decomposition of goethite and carbonaceous materials), and the mass gain due to oxidation [Fe(II) to Fe 2 O 3].Its use …

Quality requirements of iron ore for iron production
Therefore, the TI of iron-bearing materials should be > 95% + 6.3 mm and the RDI < 12% − 6.3 mm, as well as CCS > 225 kg. More fines in the shaft furnace decrease the bed permeability, leading to nonuniform gas flow and temperatures in the shaft as well as difficulties in injecting the reducing gas through the bustle.
