Abstract:
The present invention is directed to a method comprising contacting an oil sand with a suitable solvent to generate a solvated oil sand slurry; separating solvent-diluted bitumen from the solvated oil sand slurry to generate (a) a solvent-diluted bitumen and (b) a slurry with increased solids concentration; and filtering the slurry with increased solids concentration. The method of the present invention may be used to produce a low ash bitumen product and dry tailings from oil sands.
