An oil sands separator includes a drum (10) having a solids discharge end (24) and a liquid discharge end (22) and a spiral ribbon (14) having a plurality of flights wound inside the interior of the drum. The spiral ribbon extends from the solids discharge end to adjacent the liquid discharge end. A first plate (28) partially closes the solids discharge end and has a first opening (32) disposed within it. A second plate (26) partially closes the liquid discharge end and has a second opening (30) disposed within it. A conveyor (46) is provided at the liquid discharge end for conveying feed into the drum through the second opening and into at least one flight of the spiral ribbon. A pipe (50) at the solids discharge end conveys hot water into the drum through the first opening. Pockets (40) at the solids discharge end remove solids from the drum as a drive rotates the drum and its spiral ribbon. A process of releasing and separating oil from oil sand involves the steps of conveying oil sand to a feed end of a hot water bath, providing hot water to a solids discharge end, opposed to the feed end, of the separator in an amount sufficient to cover the oil sand in the separator, flowing the hot water to the oil feed end of the separator, moving the sand to the solids discharge end of the separator while gently rolling the oil sand in the hot water to release oil from the sand and allow it to separate into the hot water, removing solids from the solids discharge end of the separator; and removing the hot water and oil from the feed end of the separator.
