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 and steelmaking, which add to the energy needs of such processes.
