ABSTRACT:
The recovery of oil in an oil spill on water is achieved by a medium which not only absorbs the oil but causes it to become heavy and loose its buoyancy in relation to water so it can be made to sink, together with apparatus for effecting the deposit of the medium upon the oil in an oil spill and for collecting the sinking oil below the surface and before it attaches itself to the bottom surface so it can be removed to a place where the recovered oil may be extracted from the medium which sank the oil.
