Disclosed is a process for breaking an oil-in-water emulsion, in particular a raw emulsion produced in in situ tar sand plants, by first contacting with a polyethylene polymeric resin having a molecular weight in the range of 100,000 and 7,000,000 the raw emulsions; allowing to stand for two to four hours; adding a hydrocarbon diluent, optionally containing a larger amount of resin and then removing a mixture of diluent and oil floating on the water surface.
