Abstract
A method is disclosed for removing spilled oil from shorelines, other solid surfaces, or from the surface of a body of water by adding to the surface a mixture of fine hydrophilic mineral solids dispersed in an aqueous liquid that interacts with the oil to form buoyant mineral fines-oil floccules. These floccules reduce the tendency of the oil to adhere to solid surfaces or to recoalesce, thus facilitating dispersion and removal of the oil.
