A method is provided for separating an inert solid substantially inorganic fraction comprising sand or soil from a tarry or oily organic matter in a feedstock. The feedstock may be contaminated soil or tarry waste. The feedstock is combined with pulverized coal and water. The ratio (oil or tar to dry weight of coal) of about 1.0:10 to about 4.0:10 at a temperature in the range of 60-95°C. The mixture is agitated, the coarse particles are removed, and up to about 0.10% by weight (based on weight of coal) of a frothing agent is added. The mixture is then subjected to flotation, and the froth is removed from the mixture.
