Development Of Hematite Ore Pellet Utilizing Mill Scale

iron ore slime is generated from mines during processing and washing of iron ore, and it is not considered for pelletizing due to its excessive fineness and high gangue content, despite its good green bonding property. mill scale is generated from steel rolling mills and reheating furnaces; it has almost nil gangue content, but is not individually considered for pelletizing due to its poor hematite hematite is a red iron ore. hematite occurs in almost all forms, from solid rock to loose earth. It is the most plentiful iron ore and occurs in large quantities the effect of pelletizing taconite iron has been to encourage mines throughout the world to grind, concentrate and pelletize otherwise low-grade ores.
