Improving Availability of the Pelletization Process

The Grate-Kiln-Cooler process is a commonly used method of sintering during iron ore pel-letization, where the pellets are formed, dried, and hardened. The pellets are oxidized in the rotating Kiln, turning magnetite (Fe 3O 4)tohematite(Fe 2O 3), making the pellets attain suitable metallurgical attributes for further processing.
