Flotation as a Separation Process - Matis - - Major ...

Jul 15, 2005  Without this process, many familiar metals and inorganic raw materials would be exceedingly scarce and costly because the high‐grade ores that could be processed by simple physical and mechanical methods have long since been used up (1). Flotation initially originated from the field of mineral processing, usually termed froth flotation.

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.
