Production of iodine from caliche ore is a two-step process: 1. Extraction of iodate solutions from the caliche ore. 2. Reduction of iodate to iodine. Iodate can be extracted from ore by leaching in one of two ways depending on the ore's nitrate concentration: •Heap leaching for low nitrate containing ores.

The calculation for the third extraction is as follows: 4.07 = ( x 50mL ether) ( 0.09g − x 150 mL water) After solving the algebra, x = 0.05g. This result means 0.04g remains in the aqueous layer (0.09g − 0.05g) after the third extraction. The results of the calculations in this section are summarized in Figure 4.18.
