Iron is a common ferrous metal that has wide application in various fields, including metallurgy, chemical industry, and the manufacture of mechanical equipment [1,2].Hematite (α-Fe 2 O 3), an iron mineral that is widely distributed in nature, is an important raw material for iron smelting.It also has applications as a red pigment …
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.
