Details
Process: In reverse flotation, silica and other impurities are floated away from the iron ore. Reagents such as amines make the silica hydrophobic. The froth containing the gangue material is skimmed off, leaving a higher-grade iron concentrate. Graphite Ores: Application: Froth flotation is employed to concentrate graphite from its ore.
