  • Publication number: 20130240411
    Abstract: A device and a method for separating mixtures that contain oil or bitumen and additives. The device and the method are applicable in particular to separating stone chippings and bitumen in excavated asphalt road surfaces. In the case of oil sands and oil shale, a mineral phase can be separated from an oil phase and separation of bitumen and carrier felt can be induced in recycling of bitumen felt, oil binder and oil. The individual components of the mixture are separated from one another using a solvent, wherein the solvent takes up the oil or bitumen. The oil and bitumen are subsequently separated from the solvent so that the solvent can be reused.
