Solar Salt Production

After 40 years, Baltazar Pepito still works at the salt flats in Alubijid, Misamis Oriental. He is seen here  carrying brine to the flats, where he will collect the salt after the water has evaporated. (Source)

Solar Evaporation

Solar evaporation is probably one of the earliest methods used to produce salt. According to that process, sea water or natural brine evaporates up to the saturation point in open basins, thanks to the action of the sun and wind. Crystallization occurs in dedicated open basins as well, where the saturated brine is finally poured. Once the salt crust is formed, the exceeding water is eliminated before harvest. The raw salt may be further processed, including washing, drying, sifting and grading, if necessary and depending upon the requirements.
