Sea Salt Production Methods - Salt Production Line

SEA SALT PRODUCTION METHOD. Salt consists approximately 3.5% of the world's oceans. Shallow puddles are transformed into salt crystals with effects of sun and wind, and salt is produced naturally. When sea salt is produced industrially, it is placed in seawater condensation ponds in order to benefit from sun and wind more efficiently.
