The exploration of the second iodine-rich zone in Golestan has concluded with the discovery of 1,288 tons of proven reserves, announced the head of the northern province’s Industries, Mining and Trade Organization. Hosseinqoli Qavanlou added that only a few countries, such as the United States, China, Russia, Chile, Japan, Azerbaijan, Turkmenistan and Iran, are capable of producing iodine. He said the discovery of the reserves enables Iran to step up its iodine exports. Iodine has vast industrial applications, as it is used in pharmaceutical, auto, petrochemical, food, aerospace and electronic industries, IRNA reported.
