PROCESS FOR REDUCING THE SODIUM CHLORIDE CONTENT IN POTASSIUM CHLORIDE AND APPARATUS FOR THE IMPLEMENTATION THEREOF

摘要

The present invention relates to a process for reducing the content of sodium chloride in potassium chloride, characterized in that an aqueous suspension of potassium chloride feed crystals having a broad distribution of particle size, from about 0.1 to about 50 mum in mean diameter, in a potassium chloride saturated liquor, products which have a lower sodium chloride content than said feed crystals and have a mean diameter of The present invention also relates to a process for purifying potassium chloride by reducing the concentration of sodium chloride. / P
