    2017-12-20 · 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 agglomeration
