Iodine Production from Oilfield Brine

About 45% of the iodine currently consumed in the world comes from brines processed in Japan, the United States, the Commonwealth of Independent States (CIS; the former Soviet Union), and Indonesia. Iodine production has historically been a by-product of either oil and natural gas production or nitrate fertilizer processing.
