The next reagent that is added is the Flotation FROTHER.The frother strengthens the surface tension of the air that is injected into the flotation cell. As the air rises in the shape of bubbles, they come into contact with the mineral laden collector which attaches itself to the air.
In view of the tendency of fine gold recover by floating and the dominance of heavy minerals, the prospects for flotation were worthy of re-investigation, particularly with the new tools of the air sparged …
Although simple in concept, flotation is a complex process involving many physical and physicochemical sub-processes, each of which can significantly impact flotation efficiency. For instance, even a seemingly simple change in the flotation reagents employed can have a dramatic impact on outcomes.

These flotation reagents preferentially adsorb at the solid–liquid interface, making the surface of wanted minerals water repellent and facilitating bubble-particle attachment. They are classified based on composition and whether they exist as cations, anions or molecular species in water. Therefore, collector molecules may be ionizing compounds, which …
The most widely-used collectors in sulphide mineral flotation are the xanthates or thiocarbonates. These reagents were developed in the 1920's and played a major role in the spread of flotation throughout the world. Hydrocarbon chain length is from: ethyl C2, propyl C3, butyl C4, amyl C5 to hexyl C6. They are classified as Anionic reagents.
