Iodine was accidentally discovered by a French chemist/pharmacist in 1811. Bernard Courtois obtained a violet vapor by heating seaweed ashes with sulfuric acid as a byproduct of saltpetre (potassium nitrate). Iodine is thought to have been formed from seaweeds, oysters, and cod livers. Three iodine mining companies are currently in Oklahoma.

Typical iodine production involves a series of chemical reactions known as reduction-oxidation reactions. Oklahoma began producing iodine in 1977 by this method. Figure 2 shows a series of blow-out towers where these reactions take place. The final product is 98% pure iodine flake (Figure 3) or prill (Figure 4), which is extracted from the brine.
