CHAPTER-9 FROTH FLOTATION AND ITS APPLICATION TO ...

The flotation method of concentration, used extensively for other metal ores, has only recently been utilized for hematite iron ores. It can be applied as either the sole concentration process or as a final concentration stage to ensure a high-grade product. In the flotation process, air is bubbled through a suspension of fine iron ore in water

Froth Flotation Process - 911 Metallurgist

Jan 20, 2021  The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.
