Wet beneficiation of low grade iron ores, or tailings of ...

In the process, low grade iron ores are dry-ground, preferably to their liberation size passed through a fluidized bed roaster. The process uses coal gas for pre-heating for partial reduction. Hematite / limonite / goethite ores get converted into magnetite ore in 1-10 minutes depending on the size of iron ore, at temperatures of 500-600 degree C. The left-over heat, after reduction, is ...
