Abstract
La présente invention concerne un procédé de séparation d’au moins 3 sels solubles au départ d’une saumure comprenant lesdits sels, ledit procédé comprenant les étapes de cristallisation suivantes : a) une première cristallisation de ladite saumure, donnant une première solution concentrée F1 comprenant une solution de sel de calcium, et un solide S1 comprenant un mélange de sels de sodium et de potassium, b) une deuxième cristallisation du solide S1 préalablement solubilisé, donnant un solide S2 comprenant un sel de sodium cristallisé, et une solution F2 comprenant un mélange de sels de potassium, c) une troisième cristallisation de la solution F2, donnant un solide S3 comprenant un sel de potassium cristallisé et des eaux mères F3. L’invention concerne également une installation adaptée à la mise en œuvre du procédé de séparation selon l’invention.
