ABSTRACT:
An apparatus for separating bitumen from a bitumen froth output of a oil sands hot water extraction process comprises an inclined plate separator (IPS) for providing a first bitumen separation stage and a cyclone for providing a second bitumen separation stage. The cyclone overflow is recycled to the IPS inlet.
