Calcium iodateis an inorganic compound composed of calcium dication and iodate anion. It is a colourless salt that occurs naturally as the mineral called lautarite, which is found in the Atacama Desert in Chile.
Production and reactions
The mineral is a commercially useful precursor to iodine. Processing of the ore entails reduction of its aqueous extracts with sodium bisulfite to give sodium iodide. Via a comproportionation reaction, the sodium iodide is combined with the iodate salt to produce elemental iodine.
