PROCESS FOR THE ENRICHMENT OF MIXTURE SALTS CONTAINING POTASSIUM AND MAGNESIUM SULFATES FOR THE RECOVERY OF ANHYDROUS MAGNESIUM CHLORIDE AND POTASSIUM SULFATE

摘要

P THE PROCESS CONSISTS OF DISSOLVING MIXTURE SALTS CONTAINING POTASSIUM AND MAGNESIUM SULFATES (CARNALLITE) IN WATER, ADDING ETHYLENEGLYCOL AFTER FILTRATION TO OBTAIN AN ETHYLENEGLYCOLEAUCARNALLY-OBTAINANT SOLUTION, ANHYDROUS SOLUTION OF MAGNESIUM CHLORIDE, AND A POTASSIUM SULFATE PRECIPITE THAT IS COLLECTED. THE ANHYDROUS SOLUTION OF MAGNESIUM CHLORIDE IS TREATED WITH AMMONIA TO FORM A PRECIPITY OF MGCLNH COMPLEX WHICH IS TREATED TO CHASS NH AND OBTAIN AS A FINAL PRODUCT OF MAGNESIUM CHLORIDE TOTALLY ANHYDROUS. /P
