Bitumen sands are a natural sand or sandstone deposit which at some stage had been saturated with hydrocarbons. But which at some later stage had been exposed to conditions such that only the heavy (or long-chain) molecules remain. Or at least from which the lighter liquids and volatiles have disappeared.
Actually a very common form of hydrocarbon deposit.

What the process used to extract bitumen from oil sands is called?
The process used to extract bitumen from oil sands is called "oil sands extraction" or "bitumen extraction." This typically involves two main methods: surface mining and in-situ extraction. In surface mining, heavy machinery removes the overburden to access the oil sands, which are then processed with hot water and chemicals to separate the bitumen. In in-situ extraction, steam is injected into the ground to heat the bitumen, allowing it to flow to the surface for collection.
What technology id used to separate bitumen from sand?
The primary technology used to separate bitumen from sand in oil sands extraction is called hydrotransport, which involves mixing the sand with hot water and chemicals to create a slurry. This slurry is then processed using gravity separation techniques, such as settling tanks or flotation cells, to separate the bitumen from the sand and other impurities. Additionally, methods like steam-assisted gravity drainage (SAGD) and solvent extraction are employed for in-situ extraction, enhancing bitumen recovery from deep reserves.
How many barrels bitumen?
The number of barrels of bitumen can vary widely depending on the context, such as production rates in oil sands operations or reserves in a specific region. Bitumen is typically measured in barrels, with one barrel equating to 42 gallons. Global production can reach several million barrels per day, particularly in countries like Canada. For precise figures, it's important to refer to specific reports or data from relevant oil and gas authorities.
Difference between cut-back bitumen and emulsion bitumen?
cut black bitumen needs a solvent to dilute it whereas emulsion doesn't.
Can asphalt be defined as the combination of bitumen and aggregate?
No, within the US and Poland, asphalt is synonymous with bitumen. The correct term for a mixture of bitumen and aggregates is asphalt concrete.
What type of resources does tar sands come from?
Tar sands or oil sands are consist of clay, sand, water, and bitumen. Its bitumen content is extracted and separated to purify it into oil.
How are oil sands formed?
Oil sands are formed from a mixture of sand, water, clay, and bitumen - a heavy oil. Over millions of years, organic material decays and the bitumen collects in sand and silt deposits, creating oil sands. Heat and pressure further transform the bitumen into crude oil.
What are oil sands?
Oil sands are deposits of bitumen, sand, clay and water. Bitumen is a heavy, viscous oil that at room temperature is a lot like cold molasses. The bitumen must be diluted with lighter hydrocarbons before it is usable by refineries to produce gasoline and diesel fuels.
What is the Athabasca oil sands?
The Athabasca oil sands are large deposits of bitumen, a heavy and unconventional oil found in Northern Alberta, Canada. These reserves are one of the largest sources of oil in the world, but extracting and processing bitumen is resource-intensive and has environmental implications.
Can you describe what the oil sands are and how oil is taken out of them?
Hi Oil sands are also called tar sands or bituminous sand. To separate the Bitumen from the sand and form the bitumen oil, instead of steam, hydrocarbon solvents are injected into the sands. This is considered to be a better energy efficient system than using steam. It has environmental costs, and transport costs as it is thick. It has to be transported by road rather than pipe.
How is orimulsion formed?
Orimulsion is formed by blending natural bitumen, a heavy crude oil, with water and a small amount of surfactant to create a stable emulsion. The bitumen is usually extracted from tar sands or oil sands, and the resulting mixture has a high energy content that can be used as a fuel for power generation.
What is a mixture of clay and sand with bitumen could replace petroleum one day?
The mixture of clay, sand, and bitumen that you mention is normally known as tar sand, and there are large deposits of it in the Canadian province of Alberta, as well as a few other locations. The bitumen can be extracted from the mixture and can then be refined into petroleum products such as gasoline, etc. This is more expensive than using oil from oil wells, however, in a world of very high and ever increasing oil prices, the exploitation of tar sands has become economically viable.
What is the density of bitumen at different temperature ranges?
The density of bitumen can vary depending on the temperature. At 25°C, the density of bitumen is around 1,000 kg/m^3. As the temperature decreases, the density increases due to the bitumen becoming more viscous. Conversely, as the temperature increases, the density decreases as the bitumen becomes less viscous.
What does bitumen mean?
Bitumen sands are a natural sand or sandstone deposit which at some stage had been saturated with hydrocarbons. But which at some later stage had been exposed to conditions such that only the heavy (or long-chain) molecules remain. Or at least from which the lighter liquids and volatiles have disappeared. Actually a very common form of hydrocarbon deposit.
What are the bituminous sands in Alberta for?
Bituminous sands in Alberta, commonly referred to as oil sands, are a type of unconventional petroleum deposit that contains a mixture of sand, clay, water, and bitumen—a thick, viscous form of crude oil. These deposits are primarily located in the Athabasca, Cold Lake, and Peace River regions. The extraction and processing of bitumen from these sands are significant for Alberta's economy, contributing to energy production and employment, but they also raise environmental concerns due to the ecological impact and greenhouse gas emissions associated with extraction and refining processes.
What does bitumen eyes mean in A pale-faced figure with bitumen eyes?
It means eyes, black like coal. Bitumen is the British term for coal.
What country contains large tar sands?
Canada
