However, during the process of crystallization the product is being enriched with thallium impurity, which mainly included in a solid phase. Due to significant pollution of technogenic waste by sodium impurity during first 3-4 crystallizations, the process of displacement of other impurities is less intensive than in subsequent crystallization due to displacement of impurities into solid phase.
