Abstract:
1. A method for producing low sodium sea salt comprising: introducing a first amount of natural seawater containing sodium, chloride, potassium, magnesium, sulfate and other trace minerals into a containment structure; the containment structure being exposed to the sun; evaporating an amount of water from the natural seawater forming a brine; crystallizing an amount of sodium chloride from the brine yielding a remaining brine which includes substantial amounts of potassium, magnesium, and sulfate; separating the remaining brine from an amount of the crystallized sodium chloride; combining a second amount of natural seawater with the remaining brine forming a diluted brine; evaporating an amount of water from the diluted brine; and crystallizing sodium chloride, potassium and magnesium sulfates from the diluted brine forming a low sodium sea salt whereby the sodium chloride content is no more than 70 weight percent.
