How is salt manufactured for the shops?

1. Harvesting Salt from Salt Mines or Salt Marshes:

- Salt mining: If salt is obtained from underground salt mines, workers use various techniques to extract large salt rocks or crystals.

- Salt marsh harvesting: Seawater is evaporated in natural or man-made salt marshes or tidal flats, allowing salt crystals to form on the water surface.

2. Purification:

- The raw salt harvested from mines or marshes may contain impurities such as minerals, mud, and debris. It undergoes purification processes such as washing, screening, and filtration to remove these impurities.

3. Crushing and Grinding:

- To obtain different sizes and textures of salt, the purified salt is crushed or ground into various grades, such as coarse salt, fine salt, table salt, and rock salt.

4. Evaporation and Crystallization:

- In some cases, salt is produced by evaporating seawater in large pans or tanks. The seawater is heated to speed up the evaporation process, and salt crystals form as the water evaporates.

5. Additives and Enrichment:

- Some types of salt may be fortified with iodine or other minerals for nutritional purposes. Anti-caking agents may also be added to prevent the salt from clumping.

6. Packaging:

- The processed salt is packaged in various containers, such as bags, boxes, shaker containers, or sachets, for distribution and sale to consumers in grocery stores, supermarkets, and other retail outlets.

It's important to note that specific salt manufacturing processes may vary depending on the source of salt (such as seawater, salt mines, or underground salt domes) and the desired quality and type of salt being produced.
