Lec#5 MS - Flotation | Industrial Processes | Chemical ...

Flotation is the process of separating mixed liberated particles from each other. Slurry of hydrophobic mineral-bearing ore hydrophilic gangue is then introduced to a water bath which is aerated, creating bubbles. Particles that are not wetted by water (hydrophobic) tend to be attached to air bubbles levitate (float) to the top of the process vessel and collect in the forth layer.
