Flotation Process - an overview ScienceDirect Topics

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.
