[edit]Where does iodine come from commercially? Is it mined? Extracted from seawater? A byproduct of making Velveeta? —EncMstr 23:13, 18 March 2007 (UTC)
- From Iodine: It used to come from various minerals and from kelp. But presently "The Japanese Minami Kantō gas field east of Tokyo and the American Anadarko Basin gas field in northwest Oklahoma are the two largest such sources [of iodide-containing brine]]. ...The brine is first purified and acidified using sulfuric acid, then the iodide present is oxidised to iodine with chlorine. An iodine solution is produced, but is dilute and must be concentrated. Air is blown into the solution to evaporate the iodine, which is passed into an absorbing tower, where sulfur dioxide reduces the iodine." So, iodide comes from these wells, and then converted to iodine, which, being volatile, is more easily purified. Then the iodine is converted to various iodide salts, like that in iodized salt. --Smokefoot (talk) 17:46, 11 February 2025 (UTC)
