ABSTRACT:
A method and apparatus for detoxifying soil particles containing low melting point mineral compounds contaminated with combustible toxic materials wherein the soil particles are located without melting the low melting point mineral compounds to form combusted solids and a mixture of mineral dust and toxic material containing gas, the combusted solids are separated from the dust-gas mixture, the dust gas mixture is thereafter separated into the mineral dust and the toxic material-containing gas, and the toxic material-containing gas is then combusted at high temperature to form less harmful combustion products. The low melting point mineral compounds may be those mineral compounds of oxygen, silicon, calcium, iron and aluminum, and certain metal and metal oxides. The combustible toxic materials may be dioxin and PCB.
