iron ore processing flotation

Flotation process and equipment Flotation process is also commonly seen in nowadays iron ore beneficiation. Ithas become a very important way to recover weak magnetic ore.It is also used to treat iron ore fine to reduce the content of silica and impurities. Flotation beneficiation separates ore by different physical and chemical properties of different materials

    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
