Flotation: DAF, IAF, SAF - Veolia Water Tech

IAF is generally regarded as a flotation process where the air bubbles are 70-150 micron in size. Some manufacturers state that they have mechanisms pump veins or diffusers or other methods to make microbubbles as small or smaller than DAF systems. The "DAF" pumps are a hybrid design of IAF and DAF where air is aspirated

Then Air bubbles are created by injecting high-pressure air. Thus the sulphide ore comes on the top with the froth and oil. The remaining gangue particles which did not dissolve in oil settle down. The foam is removed and taken for further processing. Thus the minerals are separated by the froth -flotation process.
