摘要： Methods for preparing solvent-dry, stackable tailings. The method can include the steps of adding a first quantity of first solvent to a bitumen material to form a first mixture, separating a first quantity of bitumen-enriched solvent from the first mixture and thereby creating first solvent-wet tailings, adding a quantity of second solvent to first solvent-wet tailings to separate a first quantity of first solvent component from the first solvent-wet tailings and thereby producing second solvent-wet tailings, and adding a quantity of water to the second solvent-wet tailings to separate a first quantity of second solvent component from the second solvent-wet tailings and thereby forming solvent-dry, stackable tailings.

摘要： 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.

摘要： A process for separating bitumen from bitumen ore material includes extracting bitumen with a hydrocarbon solvent to produce a bitumen-enriched solvent phase and tailings. The tailings are dried or stripped in a dryer to remove any remaining hydrocarbon solvent. The amount of solvent discharged in the tailings may be less than 4 bbl per 1000 bbl of recovered bitumen.

摘要： 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.
