Summary:The present invention relates to a method for precipitating lignin from organosolv pulping liquors. For this purpose, the organosolv pulping liquor is introduced as a precipitation medium in an already existing aqueous dispersion of lignin particles or a filtrate of an aqueous dispersion of lignin particles, wherein a separate, lignin-containing phase in a dispersed state is produced.
