Salt Extraction from Desert Sand

Process Steps

The following process steps, among others, are applied:

• Mining and transportation of the raw salt to the plant
• Dissolving the raw salt, removing unwanted, insoluble components and creating an aqueous solution
• Crystallizing the salts in the aqueous solution through cooling crystallization, removing soluble components and producing Glauber’s salt (sodium sulfate with adherent water)
• Melting Glauber’s salt and producing sodium sulfate (calcination)
• Separating, drying, and packaging of sodium sulfate
• Due to the high economic efficiency of the plant and the customer’s satisfaction with the quality and robustness of the plant after more than 10 years of operation, the customer ordered two more identical plants.
