Abstract
Heavy metals contaminants in soils are fixed and rendered non-leachable by the process of heating the metal contaminated soil containing a hydrocarbon liquid, at an elevated temperature sufficient to convert at least a part of the liquid hydrocarbon into solid carbon or coke deposited on the surface of the soil and subjecting the thus heated soil to sufficient microwave radiation to sustain at least a partial fusion or melting process that results in a fixing of the heavy metals in the soil.
