Iron Ore Pelletizing Process: An Overview

In the blast furnace, iron is reduced and melted and the most common product is liquid iron called hot metal. In direct reduction, iron remains in solid state and the product is the so-called direct reduced iron (DRI). Generically, the iron ore products for ironmaking can be classified as shown in Table 1.

Influence of Oxide and Silicate Melt Phases on the RDI of ...

Blast furnace or shaft furnace feed should form a perme-able bed of material, permitting gas flow through it uni-formly at a high rate. Iron ore concentrates in the form of fines are not suitable because, fines tend to pack into a non- permeable bed and also they are likely to be carried away as dust by the high gas flow rates. The fine ore/concentrate must therefore be agglomerated into ...
