In 1801, C. Hatchett found an unknown ore while he was analyzing some chromium minerals from Connecticut. He called "columbite" to the mineral, and "columbium" to the element, once it had been discovered from an American ore. One year later, in 1802, A. G. Ekeberg discovered a new element in Finnish minerals similar to "columbite" and gave it the name tantalum. This denomination derives from the Greek god Tantalus, as a reference to the enormous difficulty in dissolving the mineral in acids.
