ABSTRACT OF THE INVENTION This invention relates to an apparatus and process for selectively precipitating crystalline sodium sulphate from a mother liquor, the mother liquor being an aqueous solution of sodium chlorate and sodium chloride, and containing dissolved sodium sulphate. The process includes diluting the mother liquor with demineralized water thus forming a diluted liquor. The diluted liquor is then chilled to a temperature Tx thereby forming a sodium sulphate crystalline precipitant, where Tx is in the range between the saturation temperature of sodium chlorate in the diluted liquor Tc and the saturation temperature of sodium sulphate in the diluted liquor Ts. The sodium sulphate crystalline precipitant is separated, through settling for example, from a resultant clarified liquor.
