Estimating the term…
A method of processing a mineral solid mixture, in particular road construction material, containing impurities with aromatic and/or aliphatic hydrocarbons, wherein the solid mixture is heated to a temperature below 570° C., wherein the solid mixture is heated in at least one heated rotating drum-like apparatus and is passed through at least one container and that the solid mixture is heated during or after the heating process, drum-like apparatus and is passed through at least one container, and in that the solid mixture is subjected to a negative pressure during heating or after heating, and in that the hydrocarbons are extracted from the heated solid mixture by the negative pressure and are rendered harmless by thermal combustion.
