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.

Design and selection of separation processes

The creation of a mixture of chemical species from the separate species is a spontaneous process that requires no energy input. The inverse process, separation of a chemical mixture into pure components, is not a spontaneous process and thus requires energy. (Seader et al., 2011). There are two kinds of mixtures: heterogeneous and homogeneous.

Research Activities Related to Flotation Process

Let us start this chapter by saying that flotation is really an old process: the historian Herodotus in ancient Greece is probably the first person that described a process similar to flotation, in the 5th century B.C., for the separation of gold particles from sand using fatty substances. And later, in the 15th century A.D., the
