    Abstract: The present invention is directed to a method which includes the steps of: 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; filtering the slurry with increased solids concentration; dropping the solids into a pressure reduction vessel wherein the pressure in the pressure reduction vessel is a pressure below a vapor pressure of the solvent; and drying the solids removed from the pressure reduction vessel to produce solids having dry tailings. The method of the present invention may be used to produce a low ash bitumen product and dry tailings from oil sands.
