Iron Ore Pelletizing Process: An Overview

2018-7-17  Bentonite, an inorganic binder, has been the main binder used in the iron ore pelletizingprocess since the beginning of pellet production in the 1950s. Bentonite promotes the forma-tion of ceramic bridges between particles, which can minimize the number of pellets thatcollapse during firing. Despite its low cost, the inorganic compounds from bentonite arecontaminants increasing the amount of acid gangue in the pellet. This increases the amount ofslag formed in iron

2013-10-1  2.3. Pelletizing of iron ore–binders. According to Moraes and Lima , pellets are obtained by adding an appropriate amount of water to a powder; 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 its handling.. This cohesive tension of fine particles due to water is called neutral tension.
