THE PROCESS FOR PRODUCING ELECTROLYABLE SUBSTANTIALLY ANHYDROUS MAGNESIUM CHLORIDE HAVING A MAGNESIUM OXIDE CONTENT OF 0.1 TO 0.5% COMPRISING THE STEPS OF ATOMIZING A CONENTRATED MASH COMPRISING MAGNESIUM CHLORIDE SOLUTION IN AN ATOMIZING TOWER BY MEANS OF COMPRESSED AIR TO YIELD A DRY POWDER, INTRODUCING INTO THE TOWER FRESH AIR HAVING A TEMPERATURE OF ABOUT 400-600* C. DURING THE ATOMIZING STEP, COLLECTING GAS ESCAPING FROM THE ATOMIZATION TOWER, SAID GAS HAVING A TEMPERATURE OF ABOUT 300 TO ABOUT 350* C. AND A STEAM CONTENT OF ABOUT 7 TO ABOUT 12% BY VOLUME, USING THE HEATED GASES ESCAPING DURING THE ATOMIZATION FOR PREHEATING THE FRESH AIR, COLLECTING THE RESULTANT SEPARATED DRY POWDER SALT MIXTURE, SAID MIXTURE CONTAINING ABOUT 2 TO ABOUT 3% BY WEIGHT OF MAGNESIUM OXIDE AND ABOUT 1 TO ABOUT 2% BY WEIGHT OF WATER, MELTING SAID RESULTANTA SEPARATED SALT MIXTURE WITHOUT BRINGING IT INTO CONTACT WITH THE ATMOSPHERE, PERMITTING SALT-CONTAINING MAGNESIUM OXIDE SEPARATED DURING THE MELTING STEP TO DEPOSIT,
