Frothers in flotation: A review of performance and function in the
Separation of mineral particles by flotation takes advantage of the wettability contrast between the surfaces of different mineral particles. In a flotation pulp, hydrophobic particles attach to air bubbles forming aggregates which float to surface of the cell, and form a layer of froth (Drzymała and Swatek, 2007), while hydrophilic particles ...
