Iron Ores (Hematite and Magnetite)
Iron Ores (Hematite and Magnetite) Iron is a metal from the periodic table’s first transition series and group 8. It is the most common element on Earth by mass, just ahead of oxygen (32.1 % and 30.1 %, respectively), forming much of the Earth’s outer and inner cores. It is the fourth most abundant element in the crust of the Earth.

The transformation of magnetite to hematite and its influence
The hard magnetite behaves in a brittle manner with a very limited operation of slip along the main crystallographic planes. The microfracturing creates an easy path for oxidation and transformation of magnetite. The newly formed hematite grains behave in a ductile manner and form a matrix of strongly oriented crystals.

Mineral and Technological Features of Magnetite–Hematite Ores
The extremely small size of hematite segregations and thin intergrowths with quartz can lead to incomplete liberation of hematite during its grinding and, as a consequence, to the concentration of the mineral in the tailings, and microinclusions of gangue minerals in hematite can significantly reduce the quality of the hematite concentrate.

Following the oxidation reaction at 275 °C, the SEM images show no evidence for the characteristic morphology of hematite, even when over half the magnetite has been oxidized to hematite. This indicates that the oxidation process at this temperature was different from that which occurred between 120 and 180 °C. Effect of stirring speed
