Abstract
Crystallization is one of the oldest unit operations known to mankind. Even today solar evaporation is still customary in regions with plentiful sunshine. Advantages are the very simple technology and a cost-free supply of energy. On the other hand, a very large surface area is needed. The rates of production per unit surface area fall in the range of 3 to 10 g/m2h. The purity of the product which can be attained in the production of salt in solar ponds is also limited. The product always consists of aggregates of single crystals which have grown together, this leading to inclusions of mother liquor and higher residual moisture. Untreated salt from solar ponds can be obtained with purities up to about 98%.
