An apparatus for processing oil sand to produce a liquid stream comprisi ng water and bitumen and a solid stream comprising solid particles, and a metho d and control system for controlling the apparatus. The apparatus includes a drum having first and second ends, a conditioning zone adjacent the first end, a compressing zone adjacen t the second end and a processing zone therebetween. A rotatable spiral trough, having liftin g members therein, extends through each zone for imparting a spiral rolling motion to the oil sand. An oil sand inlet communicates with the conditioning zone, while a water inlet communicates with the processing zone. A liquid stream outlet is located at the first end of the drum, while a solid stream outlet is located adjacent the second end. Preferably, the spiral trough has a width through the compressing zone less than through the processing zo ne and a height through at least a portion of the compressing zone greater than throu gh the processing and conditioning zones.
