Iron Ore Agglomeration Processes and their Historical

2015-12-28· These micro fines of high-grade concentrates had to be agglomerated for their use in the blast furnace and this has led to the development of the pelletizing process. These agglomerates, in turn, sharply improved blast furnace performance and led to a major shift in blast furnace burdening. History of sintering of iron ore

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
