Iodine Sources WIA World Iodine Association

Lautarite [Ca (IO 3) 2] and Dietzeite [7Ca (IO 3) 2] * 8CaCrO 4], are the two crystalline forms in which iodine naturally occurs in caliche ore with an iodine content of around 0.04% (400 ppm). To become part of the Caliche deposits, iodine was oxidized to iodate by photochemical reactions in the troposphere and at ground level in the nitrate

Iodine Wikipedia

Iodine is a chemical element with the symbol I and atomic number 53. The heaviest of the stable halogens, it exists as a semi-lustrous, non-metallic solid at standard conditions that melts to form a deep violet liquid at 114 degrees Celsius, and boils to a violet gas at 184 degrees Celsius.The element was discovered by the French chemist Bernard Courtois in 1811, and was named two years later

iodine Production and use Britannica

iodine iodine Production and use: Iodine is produced commercially from iodine-containing brines. Natural brines, or brines extracted from oil wells containing up to 150 mg per litre (0.02 ounce per gallon) of iodine, are found in Java, California, and northern Italy; the world’s top producers include Chile, Japan, China, Russia, and Azerbaijan. Impurities, such as clay, sand, and oil
