Athabasca oil sands - Wikipedia

The Athabasca oil sands, also known as the Athabasca tar sands, are large deposits of bitumen or extremely heavy crude oil, located in northeastern Alberta, Canada – roughly centred on the boomtown of Fort McMurray.These oil sands, hosted primarily in the McMurray Formation, consist of a mixture of crude bitumen (a semi-solid rock-like form of crude oil), silica sand, clay minerals, and water.

Froth Treatment Explained | Oil Sands Magazine

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