How is sodium chloide manufactured from seawater and brines?

Answer 1

Recovery and grinding.

The first step is to recover the salt from the water. You just pour the water into a shallow trough and let the water evaporate. It would be possible to boil away the water if you REALLY needed salt in a hurry, but letting the sun evaporate the water is free and has always worked well enough. This will give you salt crystals.

If you are looking for coarse salt, like Kosher salt or rock salt, this is as far as you need go. If you want to reduce it to small granules for salt shakers, you put the crystals in a grinding machine.

Answer 2

Sodium chloride, commonly known as table salt, can be manufactured from seawater and brines through a process called solar evaporation. Seawater or brines are collected and placed in shallow ponds or lagoons. The sun's heat evaporates the water, leaving behind the sodium chloride, which is then collected, refined, and processed into various forms of salt for commercial use.
