Abstract
A bitumen extraction method can include the use of a two or more mixing drums aligned in series for spraying solvent over bituminous material and/or tailings loaded in the mixing drums while the mixing drums rotate. Such mixing can result in the dissolution of bitumen into the solvent, which then allows for the separation of a “dilbit” stream from the bituminous material.
