Abstract
A process is provided for treating soil contaminated with oils, tars and light hydrocarbons. A slurry is formed with coal, water and the contaminated soil and agitated at elevated temperature, resulting in the transfer of the oil from the soil to the coal. The coal and soil mixture is then dewatered for disposal by burning or burial in a landfill.
