| Description |
A method and apparatus for extracting bitumen from tar sand utilizes a plurality of individually sealed pressure adjusted interconnected extraction chambers in which the tar sand flows countercurrent to the flow of solvent with mixing in each extraction chamber of solvent and tar sand. Tar sand is provided to the first of the extraction chambers and after removal of a portion of the bitumen is carried by a conveyor and disposed into the next chamber where further bitumen is extracted and so on through the plurality of chambers until all the bitumen is extracted and the sand and remaining solvent then conveyed into a last chamber where the sand and solvent is treated with hot water to remove solvent and pure sand is discharged. |
