    Abstract: A process for treating a bitumen froth containing bitumen, solid mineral material and water, including subjecting a first mixture containing the bitumen froth and a first amount of a paraffinic solvent to first gravity separation, thereby producing a first overflow stream and a first underflow stream, wherein the first gravity separation is performed so that the first underflow stream contains between about 5 percent and about 40 percent by weight of the asphaltenes contained in the first mixture. A second mixture containing the first underflow stream and a second amount of the paraffinic solvent is subjected to second gravity separation in order to recover bitumen from the first underflow stream.
