Oil Sands Extraction and Processing Oil Sands Extraction and Processing

Oil Sands Extraction and Processing

Once the oil sand is crushed, hot water is added so it can be pumped to the extraction plant. At the extraction plant more hot water is added to this mixture of sand, clay, bitumen, and water in a large separation vessel where settling time is provided to allow the various components to separate.
