Abstract

L'invention concerne un procédé de traitement de saumures contenant du chlorure de magnésium en présence de chlorures alcalins. Selon ce procédé, on traite les saumures par du dioxane, recueille le précipité formé et sépare le dioxane de ce précipité pour obtenir du chlorure de magnésium solide hydraté. Ce procédé permet en particulier de récupérer le chlorure de magnésium à partir de saumures ou d'eaux-mères carnallitiques.
