Minerals Yearbook, 1993: Iodine

摘要

Three producers of crude iodine supplied approximately 55% of domestic demand;the remainder was imported. Because some exports and imports are in product categories rather than crude products, net imports are not clearly developed. The major world producer, Japan, produced iodine from brines associated with gas production. The second largest producer, Chile, produced iodine as a coproduct of sodium nitrate.
