Carbon disulfide is used as a solvent to extract bitumen from oil sands in an anhydrous countercurrent flow process that is compatible with existing procedures for upgrading bitumen. The solution is then treated in a thermal reaction to reduce viscosity and then fractionated to recover the bitumen.
