Pelletizing an overview ScienceDirect Topics

Slag pelletizing is accomplished by pouring the slag stream onto a rotating drum where the slag is thrown vertically upward. The resulting slag droplets are cooled using water sprays. The pelletized product falls on the ground in a solid form and accumulates within a contained area. The wet pelletized slag is subsequently removed by a loader toTraditionally, fine ores are treated either by the process of sintering and/or by pelletizing to prepare an agglomerate with suitable metallurgical characteristics for ironmaking processes.

Bentonite, an inorganic binder, has been the main binder used in the iron ore pelletizing. process since the beginning of pellet production in the 1950s. Bentonite promotes the forma-. tion ofThe 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 low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. Iron Ore Pelletizing Process: An Overview IntechOpen
