Hydrophobic mineral get attached to air bubble and rise to the surface forming froth. Frother (flotation reagent) is added to promote the formation of a stable froth on top of the flotation cell. A flotation circuit could include three stages: rougher, scavenger and cleaning. Rougher flotation is normally the first stage in the process.
