A method of extracting bitumen from tar sands includes providing an apparatus for mixing fluids, the apparatus including: a housing, a substantially cylindrical rotor rotatably mounted within the interior chamber, a first array of spaced bores formed in the peripheral surface of the rotor, a second array of spaced bores formed in the peripheral surface of the rotor, a first fluid inlet in the housing, a second fluid inlet in the housing, and a fluid outlet in the housing positioned for withdrawal of fluid from the chamber to minimize cavitation damage at the location of the fluid outlet, and providing a separation composition at the second predetermined location, the separation composition including: a wetting agent in the amount of from about 0.001% to about 2.5% by weight of the separating composition, a hydrotropic agent, and a dispersant having flocculating characteristics, wherein the separating composition has a pH greater than 7.5.
