Flotation Frothers Frothing Agents

Jun 22 2015 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. That is surface tension.
