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.

Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and …
