US Patent 4,139,450. [10], Gantz, D.E. and Hellwege, J.W. (1977) Solvent Extraction of Oil from Tar Sands Utilizing  Water-based extraction process (WBEP) has been successfully applied to bitumen recovery from Athabasca oil sand ore deposits in Alberta. In this process, two 

Oil sands slurry produced in the Slurry Preparation Plant (SPP) contains about 50-55% sand and less than 10% bitumen. The purpose of Extraction is to recover the bitumen portion, while rejecting the heavy solids. This is achieved through a simple water-based gravity separation process, most of which occurs in a single large cone-bottomed vessel. Bitumen is too thick to pump, so light crude oil and chemicals are added. In most of Alberta, the bitumen is buried so deep that wells must be drilled to extract it, and steam injected to mobilize Sand, silt, clay, water, and about 10- 12% bitumen" is found in the makeup of tar sands. [1] Crude Bitumen is the term used when talking about oil extracted from these tar sands and this substance, crude bitumen, is a "viscous, heavy oil that will not flow to a well in its natural state". The extraction of bitumen-derived crude oil follows several steps. The first step is the extraction of the heavy oil from the rock. Tar sands (7% bitumen by weight from the tar sands) and oil shale contain relatively low concentrations of hydrocarbons. Some loss (< 10% of bitumen) occurs in the primary extraction process.

In Alberta, Canada, the oil exists in tar sands, located at varying depths from the surface. A range of extraction projects are in operation, including surface mining

Oil sands are a loose sand deposit which contain a very viscous form of petroleum known as bitumen. Oil sands are actually found all over the world and are sometimes referred to as tar sands or bituminous sands. Alberta's oil sands contain on average about 10% bitumen, 5% water and 85% solids.

In the process of separating bitumen  separation and recovery of bitumen from tar sands by digesting the raw material sample, contained in a double thickness, cellulose extraction thimble, was  12 Feb 2013 In-situ oil sands look like black, sticky sand.

Most of  22 Sep 2009 Mining is used for the bitumen that is closer to the surface (less than 75 metres), and drilling for in situ extraction is used when the bitumen is more  13 Dec 2012 Tar sands, also referred to as oil sands, are a combination of clay, sand, water, and heavy black viscous oil called bitumen. They can be extracted  6 Sep 2014 New technologies are being used to extract bitumen from oil sands. Once dug from the surface, the sand is hauled to an extraction plant  20 Sep 2007 generate the heat needed to extract bitumen from the tar sands and upgrade it into synthetic crude. The energy equivalent of one barrel of oil  After mining, the oil sands are transported to an extraction plant, where a hot water process separates the bitumen from the sand, water, and minerals.

The bitumen extraction from 50 g piece of tar sand was carried out at 50, 60 and 65 MPa and 110 °C by pure carbon dioxide and with the addition of 10 mL of fresh or salty water. The recovery decreased in the following order: with salty water, with fresh water, pure CO 2.

Instead, tar sands are mined in two main ways: [1,2] Open-pit mining – if tar sands are found near the surface, as in Alberta, Canada, they can be mined directly – much like open-pit coal mining – and then transferred to an extraction plant where the bitumen can be separated from the sand, clay, and water. In the present study, solvent extraction of bitumen from Xinjiang oil sands was investigated using solvents, such as alkanes, toluene, and chloroform, and mixed solvents, such as n-hexane–ethyl Oil sands are a loose sand deposit which contain a very viscous form of petroleum known as bitumen. Oil sands are actually found all over the world and are sometimes referred to as tar sands or bituminous sands. Alberta's oil sands contain on average about 10% bitumen, 5% water and 85% solids. The oil product extracted from Canada's tar sands isn't like conventional crude. Known as bitumen, it's sticky and so thick, it can't flow down a pipeline without extensive processing. Oil sands slurry produced in the Slurry Preparation Plant (SPP) contains about 50-55% sand and less than 10% bitumen.
