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. Before froth flotation can work, the ore to be treated is reduced to fine particles by crushing and grinding (a process known.
