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 fractionated to separate the carbon disulfide from the bitumen product. The bitumen is then treated with hydrogen to decompose the remaining carbon disulfide. The process should provide high yields and meet environmental concerns.
