Iridium, one of the rarest and most valuable elements on Earth, is primarily found in its ore form across several key regions globally. While it is not typically mined for itself, it is most commonly obtained as a valuable by-product of other major mining operations.
How Iridium is Produced Commercially
Iridium is generally produced commercially as a by-product of nickel or copper production. This means that while these base metals are the primary targets of mining, iridium is extracted during the refining process of their ores, making its availability tied to the output of these larger industries.
Key Regions for Iridium-Containing Ores
Iridium-containing ores are distributed across various parts of the world. The notable regions where these valuable deposits are found include:
- South Africa: A major global source for platinum group metals, including iridium.
- Alaska, U.S.: The United States, particularly Alaska, also contributes to the supply of iridium-bearing ores.
- Myanmar (Burma): This Southeast Asian nation is another known location for iridium deposits.
- Brazil: In South America, Brazil holds iridium resources within its mineral wealth.
- Russia: A significant player in the global mineral market, Russia also has iridium-containing ores.
- Australia: The vast mineral resources of Australia include areas where iridium can be found.
These regions represent the primary geographical areas where iridium ores are naturally occurring, underpinning its global supply chain.
Overview of Iridium Ore Locations
| Region/Country | Notes |
|---|---|
| South Africa | A prominent global source for platinum group metals, including iridium. |
| Alaska, U.S. | Contributes to the global supply of iridium-containing ores. |
| Myanmar (Burma) | Known for its natural iridium deposits. |
| Brazil | An important source of various minerals, including iridium. |
| Russia | Holds significant reserves of iridium-bearing ores. |
| Australia | Features areas with iridium deposits among its mineral wealth. |
Iridium's unique properties, such as its extreme corrosion resistance and high melting point, make it indispensable in various high-tech applications, ensuring its continued demand from these crucial source regions.
