Since 1970, extraction of of fossil fuels (coal, oil and gas) has increased from 6bn tonnes to 15bn tonnes, metals have risen by 2.7% a year, other minerals (particularly sand and gravel for ...

Mined oil sands normally contains from 7 to 13% bitumen by weight. The oil sands is trucked to the Ore Preparation Plant using large heavy haulers. A typical truck load is about 350 to 400 tonnes. Each truck dumps the oil sands load into hopper, feeding into a crusher or sizer. Oil sands mining operations run 24/7.

The mining of Canada's tar sands has destroyed large areas of sensitive wetlands in Alberta. Oil sands companies have vowed to reclaim this land, but little restoration has occurred so far and many scientists say it is virtually impossible to rebuild these complex ecosystems.

Tar sands oil is a type of thick, impure, and sludge-like crude oil that must be diluted with other toxic chemicals for transport to refineries, where it's processed into petroleum products. Producing it is more expensive and destructive than conventional oil, and the process emits 22% more carbon dioxide. Tar sands spills are also much more ...

The scale of Alberta's oil sands operations, the world's largest industrial project, is hard to grasp. Especially north of Fort McMurray, where the boreal forest has been razed and bitumen is ...

U.S. Oil Sands, which has acquired the rights to produce tar sands at mines on 50 square miles of land between Salt Lake City and Moab, Utah, plans to produce 2,000 barrels of …

What does new tar sands oil cost in per-barrel terms? In short, how high must oil prices be to make the economics favorable? Here's a mining.com report from December 14, 2012.

Tar Sands to Oil. There are two ways in which we can obtain the tar sands in order to create oil. One way is by mining on the surface (less than 100 meters deep). The second way is to heat the Bitumen causing the viscosity to decrease allowing it to flow into a well, which is …

Tar sand bitumen is a high-boiling material with little, if any, material boiling below 350°C (660°F) and the boiling range approximately equivalent to the boiling range of an atmospheric residuum. In order to correct deficiencies in nomenclature of tar sand formations and tar sand bitumen, in the United States, tar sands have been defined (FE-76-4) as

What does large scale opencast tar sand mining do to peat bogs and what does this cause? It causes them (aswell as forests) to be destroyed and there is a loss of habitats and ecosystems as a result. How much of Alberta's forests have been destroyed by tar sand extraction but why is the damage so severe?

Answer (1 of 3): Ciao Quora User, > Oil sands/tar sands in Alberta, Canada Oil sands or tar sands are sediment or sedimentary rocks consisting of sand, clay minerals, water and bitumen. Bitumen is a complex hydrocarbon which is thick and viscous. Bitumen considered as low-grade crude oil. It ha...

The extraction and refining processes related to tar sands cost companies mining tar sands in Canada approximately $27 per barrel. However, despite the extraction costs of oil from tar sands, in today's current market, with the purchase price of oil at $80 per barrel, the production of petroleum from tar sands is still an extremely profitable ...

Tar sands also impact water supplies. For every gallon of gasoline produced by tar sands, about 5.9 gallons of freshwater are consumed during the extraction, upgrading, and refining process. That's roughly three times as much as used for conventional oil. Much of this water is polluted by toxic substances harmful to human health and the ...

Tar sands mining trucks used to move the material from the mine site to the preparation facilities are 15 metres long by 7 metres tall, have 4-metre tall tires and are 40% heavier than a Boeing 747 airplane. Extracting a barrel of bitumen using surface mining requires:

Tar sands are slightly preferable to coal, but clean energy is hugely preferable to both. In order to keep the climate crisis under control, we need to transition to a clean energy economy as soon as possible. From this viewpoint, further development of the tar sands is a step in the wrong direction.

Oil sand mining has a large impact on the environment. Forests must be cleared for both open-pit and in situ mining. Pit mines can grow to more than 80 meters depth, as massive trucks remove up to 720,000 tons of sand every day. As of September 2013, roughly 895 square kilometers (345 square miles) of land had been disturbed for oil sand mining.

And it's not just forests that suffer from surface mining. For example, studies indicate that woodland caribou avoid areas within 500 meters of industrial disturbances, and will not cross cleared areas as forest is fragmented, making the ecological footprint of tar sands disturbances much larger than the physical footprint. More than 12.5 ...

Utah, which has an estimated 12 to 19 billion barrels of oil tied up in tar sands, has just issued a permit for a Canadian company, US Oil Sands, to begin mining. The company says it will use two barrels of water for each barrel of oil, and that 85% will be recovered. 15% loss might not seem like much, but Utah is in the middle of a drought ...

THE TAR SANDS The Canadian tar sands, also known as the oil sands, are the largest industrial project on earth, yet few Canadians are aware of the rapid pace of growth and its impacts on our environment, economy, and society. Tar sands operations use at least three times as much freshwater per barrel of oil as conventional oil operations.

The Alberta government estimated that in 2012, the supply cost of oil sands new mining operations was $70 to $85 per barrel, whereas the cost of new SAGD projects was $50 to $80 per barrel. These costs included capital and operating costs, royalties and taxes, plus a reasonable profit to the investors.

Data. Disturbed oil sands surface mineable area equalled roughly 895 km² in 2013, accounting for less than 1% of the total oil sands area. This makes up about 0.2% of Alberta's boreal forest, which covers over 381,000 km². By the end of 2013, the total area occupied by oil sands tailings ponds and associated structures, such as dikes, was ...

By 2004, Canadian production of tar sands oil had reached one million barrels per day—with much of the output bound for the United States—and Big Oil …

Oil sands bitumen production is comprised of in-situ (thermal and cold bitumen) production of 1.6 MMBPD and mining production of 1.5 MMBPD within the boundaries of oil sands areas.3 Total production in 2017 was 2.84 MMBPD, meaning oil sands production grew 7 percent year-overyear.

2. It is a secure source of energy. Although tar sands are not an unlimited resource, they are a relatively stable one. Even in the times of an economic downturn, mining the tar sands and extracting the bitumen continue to provide jobs, generate profits, and keep families from becoming financially desperate.

The biggest can haul in as much as 10,000 tonnes of sand an hour. A recent study estimates that 236m cubic metres of sand are taken out of …

The Opposite of Mining: Tar Sands Steam Extraction Lessens Footprint, but Environmental Costs Remain. Melting bitumen in place is less unsightly than mining tar sands, but increasing efficiency ...

Whether mining tar sands oil makes sense financially, depends on the world market price of oil—and on whether a company has already paid off …

In 2001, about 735,000 barrels per day were extracted by mining and by in-situ production from Alberta oil sands, accounting for 36 percent of Canada's total oil production. Projected 2011 production is 2.2 million barrels per day (Alberta Energy and Utility Board, 2002, Alberta's Reserves 2001 and Supply/Demand Outlook 2002-2011, Statistical ...

An existing tar sands pipeline running through the United States from Alberta, called Keystone 1, was billed as the safest pipeline in history when it was built in 2010 — yet it spilled 12 times in its first year of operation, more than any pipeline in U.S. history. Other tar sands pipelines have also spilled — with disastrous consequences.

Environment Minnesota Research & Policy Center fired a new salvo in the growing debate over frac sand mining, an industry poised for rapid expansion in Minnesota thanks to demand for silica sand used in the gas drilling practice known as fracking. The group today released a report documenting a wide range of dollars and cents costs imposed by the fracking industry.

Oil sands mining operations are conducted on a massive scale. Similarly, this photograph shows an aerial view of Syncrude Aurora tar sands mine in the Boreal Forest north of Fort McMurray, Alberta:
