Abstract: The present invention provides a method for extracting bitumen from an oil sand stream, the method including at least the steps of: (a) providing an oil sand stream; (b) contacting the oil sand stream with a liquid comprising a non-aqueous solvent thereby obtaining a solvent-diluted oil sand slurry; (c) screening the solvent-diluted oil sand slurry thereby obtaining a screened oil sand slurry and a rejects stream; (d) introducing the rejects stream into a liquid bath; (e) transporting the rejects stream through the liquid bath to a space above the surface of the liquid bath; and (f) extracting bitumen from the screened oil sand slurry obtained in step (c).

Abstract: The present invention provides an apparatus, at least comprising: a housing containing a first section, a second section and a third section; the first section having a first inlet for oil sand, a second inlet for solvent and an outlet for solvent-diluted oil sand slurry; the second section having an inlet for the solvent-diluted oil sand slurry, a screen allowing undersized material to pass and an outlet for oversized material; and the third section having an inlet for oversized material and an outlet for solvent-depleted oversized material; wherein the first section, the second section and the third section can rotate during use around a common rotation axis (A-A?).

Abstract: The present invention provides a method of filtering a solvent-containing slurry stream including: (a) providing a solvent-containing slurry stream, the solvent comprising an aliphatic hydrocarbon; (b) depositing the solvent-containing slurry stream provided in step (a) as a filter cake on a filter medium, wherein a top layer of liquid is formed on the filter cake; (c) allowing the top layer of liquid as formed in step (b) to drain through the filter cake such that substantially no liquid remains on top of the filter cake; (d) allowing a gas to partially penetrate into the filter cake thereby obtaining a filter cake with a liquid solvent-depleted top layer; (e) passing liquid solvent through the filter cake with the liquid solvent-depleted top layer as obtained in step (d) thereby obtaining a washed filter cake; (f) removing solvent from the washed filter cake as obtained in step (e) thereby obtaining a solvent-depleted filter cake; and (g) removing the solvent-depleted filter cake as obtained in step (f) fro
