ABSTRACT OF THE DISCLOSURE A method and apparatus are provided for the recovery of bitumen and bitumen wetted minerals from a mixture of bitumen, bitumen wetted minerals, water and water wetted minerals. An apertured endless belt has a top flight that is substantially horizontal and above the level of the mixture and a bottom flight that hangs in an inverted arch or catenary and is at least partly immersed in the mixture. Mixture passes through the belt apertures of the bottom flight and bitumen and bitumen wetted minerals of the mixture adhere to the belt, rise from the mixture as the belt moves, are conveyed to the top flight and fall from there into a receiver beneath the top flight. Heat or jets of fluid are used to help remove bitumen from the top flight and a pump or a bitumen conveyor is used to remove the collected bitumen for further processing.
