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.

Screening/Flotation Treatment of Combined Sewer
The processes of chemical oxidation, screening, dissolved-air flotation and disinfection were evaluated in the laboratory. It was determined that chemical oxidation was not feasible. The majority of the pollutants were of a particulate nature, which indicated solids/ liquid separation processes could possibly provide effective treatment.

Flotation and Screening Recovery of Titanium Minerals
Flotation work was conducted on two plant samples. The first was a high-titanium product containing considerable amounts of zircon and silica as quartz and aluminosilicates, and the second was a low monazite/zircon material containing high levels of silica. A three-stage process including reverse flotation was developed to treat the first sample.
