Optimization of Induration Cycle for Magnetite

2020-10-26  The oxidation of magnetite into hematite is the main reaction during preheating of magnetite, magnetite–hematite ore pellets. Oxidation always occurs first on the surface of the particles and cracks, and in formation of the lamellae type of hematite particles. The oxidation process will advance towards the pellet core with increasing temperature.
