Flotation is used in mining, food processing, water purification, paper production, medicine

 A lot of combined and special flotation methods exist. Their use is very rare. They are used in mining, food processing, water purification, paper production, medicine.

Combined flotation
Floto-gravity (Flotogravity, flotation by vibratory masses)
Floto-clasification (Flotoclassification)
Floto-jigging (Flotojigging)
Flotation / Sedimentation
Flotation / Dehydration
Flotation / Filtration
Shear-flocculation/flotation
Foam fractionation
Flotation / Magnetic separation (Murex method)
Agglomeration-floatation
 Flotation / Dense media separation

Others :
Precipitate flotation, Ion-precipitate flotation, Biological flotation, Colloidal flotation, Adsorption colloidal flotation (ACF), Flotation of microorganisms by colloidal gas aphrons (CGAs), Microflotation, Ultraflotation (or piggyback flotation
