Frothing agents are used so that the separated material is held on the surface as froth and can be removed. Frothflotation is an extensively used separation technique, having a wide range of appliions in the minerals processing industries and other industries. It can be used for particles in the size range from 50 to 400 μm.

 · Froth Treatment is a process by which water and fine solids are removed from bitumen froth using hydrocarbonbased gravity separation. There are two different types of hydrocarbons used in Froth Treatment: a naphthabased hydrocarbon and a lighter paraffinic solvent. Both produce a relatively clean bitumen product but only a paraffinic process produces a marketable product stream.

The froth is made of air bubbles, solids and water. When bubbles come into contact, the liquid film between them thins and breaks, making the bubbles coalesce [6]. With the addition of frothers, the rate of coalescence is reduced, and creating a more stable froth. The principle role of frother is the creation of fine stable bubbles.
