54.7 Summary. In this chapter, we learned that three main ferrous burden materials are used in BF operation; lump ore, sinter, and pellets. The types of iron ores used to produce these three ferrous charge materials and the related production methods were described. The various analysis methods used to determine the quality of the BF charge

1.2.2.2 Agglomeration of Iron Ore. The three major forms of iron used in ironmaking are pellets, lump, and sinter. The major change in the past 50 years has been the development of cost-effective pelletization technology allowing pellets to be a major source of iron oxide for ironmaking processes. From 1965 to 1985, the percentage of iron feed

Iron ore pellet is a kind of agglomerated fines which has better strength (expressed technically as ‘tumbling index’) as compared to that of parent ore and can be used as a substitute in blast furnaces in countries where lump ore is not available.

Description. Iron Ore (fines) Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4 ), hematite (Fe 2 O 3 ), goethite (FeO
