Worldwide, about half of all salt production comes from the sea, and about half from salt mines; in the United States, 95% is mined. Depending on how they’ve been processed, edible salts range from 98 to 99.7% sodium chloride, with the lower figures typical of table salts treated with anti-caking additives.
