ABSTRACT OF THE DISCLOSURE A system and a method for reconditioning soils contaminated with crude oils or other refined petroleum products. The system comprises a mixer input device for mixing and heating the soils with a liquid and providing a heated blended slurry. A sparger kiln agitates the slurry to break down its component parts into a fine particle slurry. A first clarifier washes the fine particle slurry to effect a first separation of oil par- ticles from the slurry. A network of flotation cell units further wash and agitate the fine particle slurry from the clarifier to effect a second separation of oil particles from the fine particle slurry, A reagent is added to the flotation cells to effect the oil separation. An aeration clarifier further separates the oil particles from the liquid mixture elected from the flotation cell units. A collecting system is provided to recover the oil particles separated from the first clarifier and the aeration clarifier. - 1 -
