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 thus iron …

For carbon neutrality, the use of sinter should be decreased owing to higher CO2 emission in the sintering process of the blast furnace operations. This trend might contribute to the increased use of iron ore pellets with lower CO2 emission in the fabrication process, high reducibility and gas permeability due to higher mechanical strength. The pelletizing process …
