Abstract
Discloses apparatus to perform a process to remove water and minerals from a bitumen froth output of a oil sands hot water extraction process. A bitumen froth feed stream is diluted with a solvent and supplied to a primary inclined plate separator stage, which separates the bitumen into an overflow stream providing a bitumen product output from the circuit and a bitumen depleted underflow stream. A primary cyclone state, a secondary inclined plate separator stage and a secondary cyclone stage further process the underflow stream to produce a secondary bitumen recovery product stream and a recycle stream. The secondary bitumen recovery product stream is incorporated into and becomes part of the circuit bitumen product output stream. The recycle stream is incorporated into the bitumen froth feed stream for reprocessing by the circuit.
