Saltudtrækning

Saltudtrækning, also known as salt extraction, is the process of obtaining salt from natural sources, primarily seawater or brine. This method has been used for centuries and remains a significant industry today. The process involves several steps: first, seawater is collected and allowed to evaporate in shallow ponds or pans. Over time, the water content reduces, leaving behind a concentrated brine solution. This brine is then further evaporated to increase its salt concentration. The final step involves crystallizing the salt, which can be done through various methods such as solar evaporation, mechanical evaporation, or freeze crystallization. The resulting salt is then harvested and processed for various uses, including food seasoning, industrial applications, and road de-icing. Salt extraction is an essential part of the global salt industry, which is valued at billions of dollars annually. It plays a crucial role in both human nutrition and various industrial processes.
