Diagram of a cylindrical froth flotation cell with camera and light used in image analysis of the froth surface. Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. . In a conventional mechanically-agitated cell, the void fraction (i.e. volume occupied by air bubbles) is low (5 to 10 percent).
