Introduction During the processing of Iron Ore, unwanted ultra-fine material typically < 150 µm is generated and is an unavoidable consequence of the crushing process.

Testing of pneumatic flotation in iron ore processing .

Under the best test conditions, an iron concentrate was obtained with a grade of 66.4% Fe and a recovery of 97.7%. Particularly, the recovery was superior in comparison to that of mechanical flotation. This was attributed to the ability of pneumatic flotation to create and maintain a relatively thick froth layer.
