Abstract

Water of the Dead Sea is unique in its chemical composition, having a very high concentration of alkaline salts, mainly Na, K, Mg and Br. The very hot and arid climate of the Dead Sea region enables separation of the different salts of the solvent in shallow open pans. A project, financed by the Israeli “Dead Sea Works” potash plant has used multitemporal thermal mapping from LANDSAT TM images to monitor the process. Analysis has shown phenomena such as improper mixing of the solution in some pans and springs of brackish water, in others, which act as inhibitors to the proper settling of salts from the solution. Furthermore, apparent setting of potash early in the process in pans intended for NaCl deposition only, has also been shown.
