A new technique being pioneered at Penn State University may serve to dramatically reduce the environmental impact of the oil extraction processes being used in Alberta. Currently, separating the “usable” oil from the tar sands involves mixing them with warm water, then agitating the mixture until it separates. This process requires literally tons of water, however, which is diverted from nearby rivers before being pumped into open-air “tailings ponds”, where the toxic sludge can leach its way back into the water table.
Instead of using warm water from diverted rivers and streams, the new method would make use of room temperature ionic liquids (ILs), which consist of salt in a liquid state. When these ILs are introduced to a tar sand mixture and agitated, the resulting combination settles into three distinct layers (below).
As you can see, the process leaves a top layer of bitumen (tar) can be easily removed and refined.
Once the process is complete and the tar is removed, the the ILs – unlike the water being used currently – can be reused, while the now tar-free sands can be returned to the environment. The good news doesn’t end there, though: because the process can make use of ILs at much lower temperatures, there are significant energy savings that come from not heating thousands of tons of water

...However, there MUST be a "better" way to extract the oil from the dirt and get at the bitumen....

Great info many thx so does this mean i should take ya off me rivals list good thing i just found a new one lol
sad thing about these new methods is they can take forever to get put through unless there is a big public outcry for it...
