Flotation Frothers - Frothing Agents

SURFACE TENSION. Froth Flotation Frothers are chemicals used to strengthen the SURFACE TENSION of an air bubble. They do not create air bubbles. To demonstrate surface tension, fill a glass of water just prior to over flowing, you will notice that the surface of the water actually extends past the lip of the glass.
