bitumen | mining | Britannica
Bitumen is also frequently called tar or pitch—though, properly speaking, tar is a byproduct of the carbonization of coal and pitch is actually obtained from the distillation of coal tar. Bitumen is defined by the U.S. Geological Survey as an extra-heavy oil with an API gravity less than 10° and a viscosity greater than 10,000 centipoise.

Asphalt - Wikipedia
About 40,000,000 tons were produced in 1984. It is obtained as the "heavy" (i.e., difficult to distill) fraction. Material with a boiling point greater than around 500 °C is considered asphalt. Vacuum distillation separates it from the other components in crude oil (such as naphtha, gasoline and diesel). The resulting material is typically further treated to extract small but valuable amounts of lub…
How is oil extracted from tar sands? - Defend The Earth
Suncor extracts bitumen in two ways: mining and in situ. Mining About 20% of Canada’s oil sands is close enough to the surface to be mined. Suncor uses large trucks and shovels to extract the oil sands that are near the surface (approx. 130-200 ft deep). Hot water is used to separate the bitumen from the sand. This step is called extraction.
What are tar sands? | American Geosciences Institute
In-situ mining – if tar sands are too deep to dig up, the bitumen can be extracted by injecting hot steam or solvents to loosen up the bitumen and allow it to flow through a well to the surface. The largest deposits of tar sands in the world are found in Alberta (Canada) and Venezuela.
What Are the Oil Sands | Canada's Oil Sands Facts,
Oil sands are a mixture of sand, water and bitumen (oil that is too heavy or thick to flow on its own). Bitumen is so thick that at room temperature it acts much like cold molasses. For that reason, this resource is sometimes called “tar sands,” but that term is incorrect because bitumen and tar (asphalt) are different compounds.

what is natural bitumen
what is natural bitumen. Natural bitumen, produced from bituminous rocks and it is a change after more than millions of years of natural mineral precipitation , under pressure and geological changes in the form of mining Having broken from the fine granular powder , light brown , where the asphalt content of about 80% to 85% , the rest are kind of limestone minerals.
Understanding the Properties of Bitumen Froth from Oil,
24-11-2021· Bitumen froth, as the crude product from the surface mining of oil sands, requires the efficient removal of water and solids for further processing. This work has systematically characterized the properties of bitumen froth from an oil sands operation in Northern Alberta and their correlation to the froth treatment efficiency (i.e., removal of water and demulsification

IN-SITU. About 80% of Alberta's bitumen reserves are too deep to be mined and must be extracted in-place (or in-situ) using steam. Bitumen is heated and pumped out of the ground, leaving most of the solids behind. In-situ extraction has a much smaller footprint than oil sands mining, uses less water, and does not produce a tailings stream. May 1.
