  • 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 1Jul 10, 2017· The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries However, the content of iron in ore deposits has deteriorated and lowgrade iron ore has been processed The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking This chapter shows the status of the pelletizing processIron Ore Pelletizing Process: An Overview | IntechOpenAs shown in Figure 1 , China presents the largest production capacity, followed by the United States and Brazil The iron ore pelletizing process consists of three main steps: 1 Pelletizing feed preparation and mixing: the raw material (iron ore concentrate, additivesIron Ore Pelletizing Process: An Overview
