  • Flotation Froth - an overview ScienceDirect Topics

    An example of foams with a significant amount of solid phase are liquid foam-concrete mixtures and flotation froths. In flotation froths there is usually more than 30% solid phase and immediately after their formation the content of solids in them can be over 70% [83]. Other foams can also contain solid particles but there presence is often undesirable.
