salt extraction

Salt extraction involves collecting salt from natural sources such as saltwater bodies or underground deposits. Common methods include evaporating seawater in large, shallow ponds until the salt crystals form and can be gathered, or mining rock salt from underground mines where salt deposits have mineralized over millions of years. The process often includes filtering, purification, and drying to produce edible or industrial-grade salt. Overall, salt extraction transforms natural salt sources into a clean, processed product used in food, manufacturing, and other industries.
