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.

Sinter Quality and Process of Sintering Iron Ores –

The ore particle size plays an important role. The assimilation ability of fine ores is greater than that of coarse particles. The reaction surface area of iron ore fines is high which results into higher reaction rates. But, the formation of higher concentrations of melt result into decrease in the melt fluidity.

Iron ore - Wikipedia

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 color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)n(H 2 O), 55% Fe) or siderite (FeCO ...
