Abstract
A system and method for immediately separating oil sands into three layers uses a logwasher with paddles that mixes the oil sands with hot water and steam. The three layers of bitumen, clay/sand/water slurry and rock separate effectively and immediately and are not re-mixed in further processing as was conventional, further producing a clay fraction from the fines for mineral processing.
