Abstract: The present application provides a method for bitumen froth treatment in the transition region between coalescence and agglomeration. The method involves separating diluted bitumen product from a bitumen froth mixture, comprising the bitumen, water and mineral solids, the method comprising: (a) combining the mixture with a solvent blend to obtain a combination having a ratio of said solvent blend to the bitumen of about 1.0-1.6 by mass, wherein said solvent blend comprises from 2.2-4.5 (±0.2) wt % aromatic solvent or from 70-80 (±10) wt % paraffinic solvent; (b) mixing the combination; and (c) separating the diluted bitumen product from the water and mineral solids.
