ABSTRACT:
A process is disclosed for the production of potassium sulfate from potassium chloride by means of a sulfate-laden anion exchanger, according to which as reaction solution, the exchanger is intensively contacted with a saturated potassium chloride solution, after saturation with potassium sulfate, and thereupon again separated, whereupon from this solution the crystals formed therein are separated, while the depleted anion exchanger is regenerated by intensive contact with a magnesium sulfate solution.
