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.
