Hematite is one of the most abundant minerals on Earth's surface and in the shallow crust. It is an iron oxide with a chemical composition of Fe 2 O 3. It is a common rock-forming mineral found in sedimentary, metamorphic, and igneous rocks at locations throughout the world. Hematite is the most important ore of iron.
In order to obtain an overall picture of the in-flight reduction process of fine iron ore, a series of experiments have been carried out at different temperatures with the typical gas composition (PCR2′: 42.2% CO + 57.8% CO 2) and typical particle size (45–53 μm). Furthermore, the morphology analysis and kinetic analysis has been conducted.
