In 2023, the world's total reserves of tantalum amounted to an estimated 390,000 metric tons, which is the sum of the reserves in China, Australia, and Brazil – the only countries for which data was available.
Previously known as tantalium, tantalum is a rare transition metal that is hard, blue-gray in color, and lustrous. It is highly resistant to corrosion, which makes it invaluable for high-temperature applications such as in electrical devices and aircraft engines, as well as with handling corrosive chemicals.
Reserves of tantalum worldwide from 2010 to 2023
(in 1,000 metric tons)
* Figure for 2021 represents the sum of the stated reserve values for Australia and Brazil, while figures for 2022 and 2023 are the sum of the stated reserve values provided for Australia, Brazil, and China. This is because the report stated that the world total reserve figures for those years is "not available" and these were the only countries for which data was provided. Therefore figures for 2021, 2022, and 2023 are incomplete estimates.
According to the source, the actual figures for 2012 through 2020 are all greater than the stated figures to an unspecified degree.
