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.

WWF's Koehnken says that "rivers can sustain sand extraction." But there are limits. The amount mined, she says, should be "within the natural variability of the sediment load of the system." That suggests a simple rule that could be applied around the world. Sand mining in rivers should not exceed the rate of resupply of sand from ...

In fact, Utah contains approximately 55% of the nation's total deposits. These oil sands are classed as "oil-wet" deposits and consist of a mixture of sand and a dense, extremely viscous form of petroleum technically referred to as bitumen or tar. Moreover, the bitumen in Utah is somewhat unique in that it contains less than 0.5% sulfur.
