Abstract: The invention relates to a method for the continuous extraction of lactic acid from an aqueous suspension containing solids. According to said method, the aqueous suspension containing solids is brought into contact, in a counter-current, with an organic solvent that is partially miscible with water, in a column provided with filling agents which have a surface consisting of hydrophobic material, in such a way as to form an aqueous phase and an organic phase, such that the organic phase is guided as a dispersed phase in a section of the column comprising filling agents.
