Abstract Iron ore, pellets, and sinter were reduced with hydrogen at 800 °C to understand the degree of reduction and the mineralogical aspects. The weight loss of goethite and limonite iron ore was noticed to be lower than that of magnetite and hematite varieties. Xray diffractometry (XRD) indicated 100 pct Fe in the case of hematite, 93 pct in magnetite, 53 pct in goethite, and as low as ...

Granulation and sintering are the two most important steps of the iron ore agglomeration process to produce sintered ore. Since granulation takes place at room temperature and is mainly characterized by physical and interfacial phenomena, while sintering is a thermal densification process involving extensive chemical reactions, the characteristics of the ore blends during these processes are ...
