In situ desorption experiments revealed that a large fraction of the Atrac was weakly attached to the hematite surface, as it was partially removed by flushing with water at pH 8.5 and 10. These results suggest that a separate washing unit after the flotation step could be beneficial in reducing the contamination of iron ore by flotation chemicals.

When iron oxide is to be separated from the siliceous gangue, either direct or reverse flotation can be applied. Anionic collectors such as fatty acids and alkyl sulfates and sulfonates are most commonly used to flotate iron oxides from siliceous gangue minerals at pH values where the surface of iron oxide is positively charged.
