Reducing energy consumption during bitumen separation from …
Two different methods of producing oil from oil sands exist: open-pit mining and in situ. Approximately 20% of oil sands are recoverable through open-pit mining. After oil sand is mined, bitumen is separated from solids and water within the bitumen production facilities. The process of bitumen separation consists of 3 main steps.

The impact of oil sands on the environment and health
There are two primary extraction methods for oil sands: open-pit mining and in-situ mining. The technique used depends on the depth of the deposit. For example, in-situ mining is used when bitumen lies too deep beneath the surface for open-pit mining. Injection of steam is used in both methods to heat the bitumen, which serves to make it …

To extract the bitumen in the oil sands, conventional oil drilling techniques cannot be used because bitumen is too heavy to be pumped and sticks to sand grains. Therefore other extraction techniques have been developed. The most common methods to extract bitumen are open-pit mining and in-situ, which is Latin for 'in place'.

Oil Sands Processes
The accessible ore of oil sands is located 50 to 200 m from the surface. Due to the difference in depth, recovery of oil sands ore calls for different techniques: open pit mining for shallow resources and steam assisted gravity drainage (SAGD) for deeper resources. These two oil sands processes techniques are described in more detail below.
