Feb 01, 2005· Quartz is the major gangue mineral present in iron ores. Flotation is the usual concentration method employed for the ores in the fine size range (<149 μm). Different flotation routes are available: (i) reverse cationic flotation of quartz; (ii) direct anionic flotation of iron oxides; (iii) reverse anionic flotation of activated quartz.

tflotation cell iron ore processing plant

Iron oxide particles stick to the air bubbles and float. Floated and concentrated iron ore slurry is then skimmed from the surface of the bath, and water is removed using a filter press. If the desired iron content is not achieved, the process is repeated. A modifier is added in some cases to enhance the performance of the collector.

Bridging Theory And Practice In Iron Ore Flotation

Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to
