A revolving drum containing a multitude of oleophilic mechanical surfaces in fixed relationship with the inside drum walls is used to increase the particle size of bitumen phase in an aqueous mixture. The mixture tumbles in the drum and the mechanical surfaces, passing through the mixture, capture bitumen phase particles that accumulate on these surfaces and increase in size until they are sloughed off these surfaces back into the mixture in the form of enlarged bitumen phase particles. When the water phase of the mixture is relatively low in minerals content, the revolving drum and its mechanical surfaces are used to transfer water wetted mineral particles from the bitumen phase to the aqueous phase of the mixture, resulting in a bitumen phase with reduced minerals content.
