Here is the list of countries that produce the most iridium in the world. We notice that very few countries have iridium mines. This metal is much rarer than palladium or platinum. Which means that its price is much higher: 5 times higher than that of platinum and 4 times higher than that of palladium. We note that South Africa produces the majority of iridium in the world.
Iridium is mainly used in electrodes to produce chlorine. The metal is also present in OLED screens, crucibles (pots allowing the fusion of metals), catalysts (for the carbonylation of methanol to produce acetic acid), spark plugs (for the electrical system of planes).
