Kinetics of hematite to magnetite transformation by ...


The kinetic analysis indicated that the reduction of hematite ore to magnetite is a single-step process, which can be described using the first-order reaction model. The reaction rate decreased when exposure time increased. The reaction rate constant increased by more than 20 times with increasing temperature from 300 to 600 °C.

Hematite - Wikipedia


Hematite, also spelled as haematite, is a common iron oxide with the formula Fe 2 O 3 and is widespread in rocks and soils. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum. Hematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F).
