Abstract
Methods and system for extracting bitumen can include the use of a mixing drum for spraying solvent over bituminous material to help dissolve bitumen and create a bitumen-laden solvent phase that can be separated from the non-bituminous components of the bituminous material. The mixing drum can be rotating during the spraying step to help promote dissolution of bitumen. The mixing drum can also include an internal screen for separating bitumen-laden solvent from the non-bituminous material. In some embodiments, two or more mixing drums are used in series, with the non-bituminous material from the first mixing drum being sprayed with additional solvent in the second mixing drum and bitumen laden solvent from the second mixing drum being used as the solvent sprayed over bituminous material in the first mixing drum. Hydrocyclones can also be incorporated in the in system and methods for increased extraction efficiency.
