Flotation Cell
Agitated flotation (or mechanically agitated flotation) is a widely used mineral processing technique that separates valuable minerals from waste material (gangue) by using a mechanical impeller to mix a slurry and disperse air bubbles.
The process occurs within a mechanical flotation cell, which typically consists of a large tank (up to 250 m³) and a rotor-stator assembly at the bottom.
- Agitation: A high-speed impeller creates a turbulent hydrodynamic environment that keeps mineral particles in suspension and prevents sedimentation.
- Aeration: Air is either drawn into the cell by the vacuum created by the impeller (induced-air) or forced in via an external blower.
- Separation: Hydrophobic (water-repelling) particles attach to the rising air bubbles and float to the surface to form a mineral-rich froth, which is then skimmed off.
