2/1/2012 · Iodine reactions with the sulfide and the ferrous minerals of ore are the main consumers of iodine in solution. At iodide concentrations of less than 4 g/L, the dissolved free iodine in solution in the presence of ore was less than that in pure water. This was attributed to the equilibrium adsorption of iodine on the ore surface.

Resublimed iodine is usually 99.9% pure. Most iodine is converted for industrial use to potassium iodide, sodium iodide, and other inorganic compounds, as well as numerous organic compounds. Geology-Resources Iodine occurs in rocks and soils, surface and underground brines, and caliche ores.
Mineral Resource of the Month: Iodine | EARTH Magazine
The caliche ore, for example, has a typical iodine content of about 0.04 percent (400 parts per million). Before the development of iodine extraction from caliche, seaweed, especially from off the coast of China, was an important source. Iodine is obtained as a byproduct in the processing of sodium alginate.
Mineral Classification, An Organizational Necessity
Mineral classification can be an organizational nightmare. With over 3,000 different types of minerals a system is needed to make sense of them all. Mineralogists group minerals into families based on their chemical composition. There are different grouping systems in use but the Dana system is the most commonly used.
Evidence for the chalcophile nature of iodine - ScienceDirect
High values of iodine have been found in some ore minerals and sulphide-containing carbonatites, suggesting a chalcophile nature. On the evidence of cold-water-soluble iodine contents of sulphide minerals it is sug- gested that in most cases at least 75% of the total iodine is strongly bound in these minerals.

Iodine - Essential Chemical Industry
(b) From nitrate ores. In Chile, iodine occurs in nitrate deposits as iodate ions (IO 3-). The ore contains approximately 95% sodium nitrate and 5% sodium iodate, NaIO 3. After the removal of sodium nitrate by crystallization, the crushed ore is leached with hot water. The clear solution, in which the iodate ions accumulate, is run off and cooled.
