A method of processing oil sands material including bitumen. The method includes subjecting the oil sands material to a predistillation process. The predistillation process includes heating the oil sands material to between approximately 350° C. and approximately 400° C., to produce atmospheric gas oil from the bitumen, and intermediate dried oil sands material, and heating the intermediate dried oil sands material to between approximately 535° C. and at least approximately 600° C., to produce vacuum gas oil and coked oil sands material comprising carbon-heavy hydrocarbons and sand. The method also includes subjecting the coked oil sands material to gasification, to produce barren hot oil sands material, and syngas comprising hydrogen and carbon monoxide gases.
