ABSTRACT:
A method and apparatus for producing oil, bitumen, precious metals, and hydrocarbon gases from mined oil-bearing rock material, such as tar sands and soil shale. The rock is ground, preconditioned in a heated and pressurized atmosphere devoid of oxygen, and subsequently centrifuged in the presence of an oil-replacement gas to produce oil, and also any precious metal particles that are present in the oil-bearing rock material. The produced oil and precious metals are subsequently separated from each other by centrifuging.
