Abstract
The present invention is an improved method for crystallizing inorganic salts. The inorganic salts that are suitable for this process are characterized by the fact that they form isothermic or polythermic concave solubility curves. Each concave solubility curve represents saturated concentrations of the salt that is desired to be purified versus either concentrations of a second, different inorganic salt or versus temperature.
