Iron ore sintering and pelletizing are the predominant processes in the ironmaking industry [1,2]. During the iron ore sintering process, calcium ferrite phase is believed to be the most desirable bonding phase because it has high reducibility and sufficient mechanical strength [3–5]. The sintering process can be divided into three procedures: (1) heatingup period.
Iron ore supply, especially highgrade pellets, have been restricted since late2015, when a mining tailings dam collapsed in Brazil and caused the closure of over 20 million tons per year of production.
