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 .
