Extraction procedure by means of solvents in which the material is treated in a series of successive phases with a different portion of solvent in each phase, which in each phase is progressively enriched to a predetermined concentration of the component to be extracted from the material then withdrawing from the process, and carrying out this solvent enrichment by repeatedly mixing the solvent and the material as it passes through the phase, in a proportion such that the volume ratio between solvent and material in the mixture is substantially greater than the overall ratio of extraction, that is the ratio in volume between the total amount of solvent removed and the amount of material passing through the various phases to give the solvent the indicated concentration indicated.
