ABSTRACT OF THE DISCLOSURE A process for recovering oil from stabilized oil- in-water petroleum emulsions by subjecting them to the action of an optimum amount of non-ionic, water-soluble, ultra-high molecular weight polyalkylene oxide resins at a pH of 7 to 10, and then adding a saturated aqueous alkali metal halide solution. The process is carried out at between 60°F and 210°F and the mixture is allowed to stand in the quiescent state for a period of 3 to 12 hours to allow the halide solution to increase the specific gravity of the resulting aqueous phase by at least 0.019 thereby causing the bitumen to float thereabove to facilitate recovery thereof.
