Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

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.
