Flotation Froth - an overview ScienceDirect Topics

The control of flotation froth in mineral processing can be adversely affected if hydrophobed mineral particles too readily destabilize the froth. Formation of undesirable foam can also be an aspect of the use of certain formulated products such as waterborne latex paints, and detergents for use with machine washing of textiles and dishes.
