Chemical information in the article confused

Rock salt is sodium chloride, not calcium chloride. Calcium chloride is probably not a typical product of salt plants (though the product from evaporite brines may be different from sea brines). Sodium carbonate is not a typical product either but sodium carbonate or at least sodium hydrogen carbonate is a product of some evaporites. There are chemical processes for making sodium carbonate from sodium chloride, may be there was such production at the site? The Solvay process produces calcium chloride as a byproduct. Sodium carbonate is not processed into calcium hydroxide (which isn't lye) but calcium hydroxide can be used to make (caustication) sodium hydroxide (lye) from sodium cabonate. Someone with knowledge of this plant should make the article more accurate.150.227.15.253 (talk) 18:39, 9 December 2018 (UTC)[reply]
