  What are tar sands? | American Geosciences Institute

  3  · 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-situ mining – if tar sands are too deep to dig up, the bitumen can be extracted by injecting hot …
