SC - Re: Sea salt

[James F. Johnson]

Trying to find out the mineral content of sea salt on the Web is mostly
turning up companies that sell sea salt as an alternative to table salt.
One actually gave some numbers. Redmond Minerals, in Redmond, Utah, USA,
mines their salt from a Jurassic age sea deposit. They say it contains
over the various deposit:

Sodium Chloride		98.32%
Calcium 		.40%
Potassium		.12%
Sulfur			.11%
Iron			.06%
Phosphorus		.05%
Iodine			.002%
Manganese		.0015%
Copper			.001%
Zinc			.0006%

Generally, the tone is there are 72-84 minerals in sea salt, whether
evaporated or mined from a sea deposit, including sodium and chlorine
(NaCl). The commercial refining process removes all these except the
NaCl. If it's the 5% sold for food consumption, anti-caking agents are
added, possibly the sugar for taste, and potassium iodide to prevent
goiter.
