Salt Extraction Process from Sea Water
Salt is commonly obtained from sea water through the process of evaporation. Here is a detailed explanation of how this extraction process takes place:

1. Collection of Sea Water
Sea water is collected from the ocean and transported to salt evaporation ponds or pans.

2. Evaporation
The collected sea water is then poured into large shallow ponds where it is left to evaporate under the sun. As the water evaporates, salt crystals begin to form.

3. Crystallization
As the concentration of salt in the water increases due to evaporation, salt crystals start to precipitate out of the solution and settle at the bottom of the ponds.

4. Harvesting
Once a sufficient amount of salt crystals has formed, the salt is harvested by carefully scraping it from the bottom of the ponds. The salt is then washed and dried to remove any remaining impurities.

5. Refining
The harvested salt may undergo further refining processes to improve its purity and quality. This may involve crushing, grinding, and additional washing steps.

6. Packaging
The final step involves packaging the refined salt for distribution and sale to consumers for various purposes such as food preservation, seasoning, and industrial applications.
By following these steps, common salt can be efficiently extracted from sea water through a natural evaporation process.
