Introduction to Iron ore Pellets and Pelletizing processes

It is an agglomerating process of converting iron ore fines into 'uniformed sized iron ore pellets' which can be charged directly into a blast furnace (BF) or into a vertical furnace or rotary kiln normally used for the production of direct reduced iron (DRI). The iron ore pellets are shown in Fig 1.

Blast Furnace Process

Nowadays, over 93% of the total iron production from ores is taking place via BF route. An alternative route for iron production is direct reduction, which is described more thoroughly in a separate chapter. Figure 1.1.1 illustrates the position of the blast furnace as well as direct reduction in the overall steelmaking process [8].
