Abstract

L'invention concerne un procédé de production d'acide lactique, et de séparation et/ou récupération d'acide lactique dans une solution de charge au lactate. On combine une solution de charge au lactate (14) obtenue, de préférence, à partir d'un bouillon de fermentation (10), avec un agent d'extraction, avant de l'extraire (18) de la phase organique résultante (21). Le carbonate ou le bicarbonate (29) récupéré dans la phase aqueuse (20) est de préférence recyclé vers le fermenteur (10), l'agent d'extraction régénéré (17) étant, de préférence, recyclé (24) pour être utilisé dans l'extraction.
