wet processing of iron ores
Wet beneficiation of low grade iron ores, or tailings of ...
The efficiency of iron recovery is 90-95% (as against 70-75% in the conventional beneficiation plants) & the left-over Fe in the tailings is only 10-15% (as against 35-45% in the conventional beneficiation plants). In the process, low grade iron ores are dry-ground, preferably to their liberation size & passed through a fluidized bed roaster.
