Abstract

L'invention concerne la récupération de substances dissoutes dans des solutions aqueuses. Elle concerne notamment un procédé à membrane liquide pour récupérer des espèces chimiques dissoutes dans des solutions aqueuses en utilisant une émulsion appropriée, une précipitation électrostatique pouvant être utilisée pour récupérer l'espèce de la phase intérieure de l'émulsion. On prépare l'émulsion de façon que sa phase intérieure se compose de gouttelettes dont les dimensions se situent entre environ 0,3 et 10 mu , la majorité des gouttelettes étant comprise entre 0,8 et 3 mu . On utilise, de préférence, un champ électrostatique ayant, de préférence, une intensité d'au moins 1 kilovolt par centimètre et pouvant atteindre 7,5 kilovolts ou plus. L'invention s'applique en particulier à la récupération des substances ioniques et, en particulier, des ions métalliques, contenus dans certaines solutions industrielles.
