The attachment of particles to bubbles is the most important sub process in flotation. Without a selective attachment, no separation would be possible. To enhance this selective attachment, surfactants may be added to alter surface properties. The surfactants control the surface tension and contact angles of the particles in the flotation process.

Flotation processes are based on the different surface wettability properties of materials (Wang et al., 2015). In principle, flotation works very similarly to a sink and float process, where the density characteristics of the materials, with respect to that of the medium where they are placed are at the base of the separation.
