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.
