Systems and methods for oil sands processing
Abstract:
The systems and methods described herein provide for extracting bitumen from oil sands at ambient or subambient temperature, for example at temperatures between 0 degrees Centigrade and about 20 degrees Centigrade. The process includes the steps of forming a slurry by mixing the oil sands with water, adding an extractant to the slurry, agitating the extractant with the slurry, and collecting bitumen that separates from the slurry.
