U.S. Oil Sands’ water-and-energy-intensive extraction process involves first digging up congealed tar sands, then crushing them to reduce their size. The company then mixes the crushed sand with large amounts of hot water (at a temperature of 122-176°F) to loosen up and liquefy the tarry, oil-containing residue and separating it from the sand. Next, coarse solids sink, are subsequently removed and considered waste tailings. Air is then bubbled through the remaining water-oil mixture, which makes the oil float to the top in what’s referred to as "bitumen froth," in industry lingo. The froth is then deaerated, meaning all the air molecules are removed. When it finally gets to this point in the production process, the mixture is still so thick it can’t be pumped through pipelines.
