Process for the separation and recovery of inorganic salts

Claim 1

A PROCESS FOR THE SEPARATION OF SODIUM CHLORITE AND POTASSIUM CHLORATE FROM SOLUTIONS CONTAINING THESE SALTS WHICH COMPRISES PROGRESSIVELY EVAPORATING THE SOLUTION AT TEMPERATURES ABOVE 34*C. SO AS TO CRYSTALLIZE POTASSIUM CHLORATE UNTIL THE SOLUTION REACHES THE EUTECTIC COMPOSITION HAVING A SATURATION TEMPERATURE OF ABOUT 34*C., SEPARATING THE THUS CRYSTALLIZED POTASSIUM CHLORATE, THEREAFTER COOLING THE REMAINING SOLUTION BELOW 34*C. TO CRYSTALLIZE A MIXTURE OF POTASSIUM CHLORATE AND NACLO2$3H2O, SEPARATING THE MIXTURE FROM THE MOTHER LIQUOR, HEATING THE MIXTURE ABOVE THE TRANSITION POINT OF NACLO2$EH2O TO DISSOLVE THE POTASSIUM CHLORATE AND TO FORM A SLURRY OF SOLID ANHYDROUS SODIUM CHLORITE IN A SATURATED SOLUTION THEREOF, AND SEPARATING THE SOLID SODIUM CHLORITE FROM THE HEATED SOLUTION.
