Quality requirements of iron ore for iron production
The integrated iron- and steelmaking route involves blast furnace (BF) ironmaking followed by basic oxygen steelmaking (BOS). The BF uses sinter, pellet, and lump ore as the iron-bearing raw materials and coke and pulverized coal as reducing agents to produce hot metal with consistent quality for the BOS process.

Study and Implementation of Quality Improvement …
Cold crushing strength (CCS) of iron ore pellets varies widely from as low as 80 Kgf / pellets to as high as 350 Kgf /pellets depending upon the input material quality and the process variables. The most preferred range of CCS of iron ore pellets is 180-240 Kg f / pellets which were normally found in the proportion of 35-40% at the plant.
