ABSTRACT:
An extraction vessel is provided with an inlet channel and an outlet channel. The inlet channel is adapted for introduction of carbonaceous material in molten lead into the extraction vessel which is at least partially filled with molten lead. Solvent introduced into the extraction vessel extracts the carbonaceous material floating upwardly in the vessel. From the vessel extracted solids are removed separately through the outlet channel. Solvent and extracted material is removed from the extraction vessel by means of a conduit.
