How Salt Is Produced: Mining and Evaporation, Not "Making" from Water

Salt isn't "made from water"—rather, it's extracted from two primary natural sources through distinct processes:

Rock Salt Mining

Underground deposits of halite (rock salt) formed from ancient evaporated seas are mined using traditional shaft mining or solution mining. In solution mining, water is injected to dissolve the salt, creating brine that's pumped out and evaporated. Major producers include the U.S., China, Germany, and Canada.

Sea Salt Evaporation

Seawater (averaging 3.5% salinity) is channeled into shallow evaporation ponds. Sun and wind concentrate the brine through successive ponds until salt crystallizes. This solar evaporation method produces sea salt with trace minerals that affect flavor and texture. Traditional salt pans operate in Mediterranean countries, Australia, India, and elsewhere.

Key Distinction

Water is the medium for sea salt production, not the source material—the dissolved minerals originate from geological weathering carried to oceans by rivers over millions of years. The salt itself already exists in solution; evaporation simply separates it.
