Iron Ore Pelletizing Process: An Overview
Pellets are obtained byadding an appropriate amount of water to the iron ore concentrate; this is a fundamental factor in the formation and growth of pellets, which creates a surface tension that holds the mineral grains cohesive, thus allowing their handling [6, 8]. This cohesive tension of fine particles due to water is called neutral tension.
