Abstract

L'INVENTION DECRIT UN PROCEDE DE TRANSFORMATION D'UN QUELCONQUE SULFATE OU CHLORURE, SEL DOUBLE OU MELANGES CONTENANT DU MAGNESIUM, EN CHLORURE DE MAGNESIUM ANHYDRE DE PURETE EXCEPTIONNELLEMENT ELEVEE TOUT EN RECUPERANT SIMULTANEMENT DU SULFATE DE POTASSIUM DE QUALITE ENGRAIS OU EN RECUPERANT DU CHLORURE DE POTASSIUM ANHYDRE INTERESSANT SUR LE PLAN ECONOMIQUE. IL EST EGALEMENT DECRIT UN PROCEDE COMBINE QUI PERMET D'UTILISER LE CHLORURE DE POTASSIUM ANHYDRE OBTENU PAR ENRICHISSEMENT D'UN SEL DOUBLE DE TYPE CARNALLITE, POUR AMELIORER L'ASPECT ECONOMIQUE DE LA RECUPERATION DU CHLORURE DE MAGNESIUM ANHYDRE A PARTIR D'UN SEL MIXTE CONTENANT DU SULFATE DE MAGNESIUM ET DU SULFATE DE POTASSIUM.THE INVENTION DESCRIBES A PROCESS FOR THE CONVERSION OF ANY SULFATE OR CHLORIDE, DOUBLE SALT OR MIXTURES CONTAINING MAGNESIUM, INTO MAGNESIUM CHLORIDE EXCEPTIONALLY HIGH PURE ANHYDROUS WHILE RECOVERING SIMULTANEOUSLY FROM THE SULFUROUS BULK OR SULFUROUS PULP. ECONOMICALLY INTERESTING ANHYDROUS POTASSIUM. IT IS ALSO DESCRIBED A COMBINED PROCESS WHICH ALLOWS TO USE THE ANHYDROUS POTASSIUM CHLORIDE OBTAINED BY ENRICHMENT OF A DOUBLE CARNALLITE TYPE SALT, TO IMPROVE THE ECONOMIC ASPECT OF THE RECOVERY OF ANHYDROUS MAGNESIUM CHLORIDE CONTAINING MAGNESIUM SULFATE AND POTASSIUM SULFATE.
