At the beginning of the 20th century, a large deposit of vanadium ore was discovered near Junín, Cerro de Pasco, Peru (now the Minas Ragra vanadium mine). [ 55 ] [ 56 ] [ 57 ] For several years this patrónite (VS 4 ) [ 58 ] deposit was an economically significant source for vanadium ore.
Nils Gabriel Sefström (2 June 1787 – 30 November 1845) was a Swedish chemist.Sefström was a student of Berzelius and, when studying the brittleness of steel in 1830, he rediscovered a new chemical element, to which he gave the name vanadium.
Andrés Manuel del Río y Fernández (10 November 1764 – 23 March 1849) was a Spanish scientist, naturalist and engineer who discovered compounds of vanadium in 1801. He proposed that the element be given the name panchromium, or later, erythronium, but his discovery was not credited at the time, and his names were not used.
The discoveries of the 118 chemical elements known to exist as of 2025 are presented here in chronological order. The elements are listed generally in the order in which each was first defined as the pure element, as the exact date of discovery of most elements cannot be accurately determined.
In 1830, Nils Gabriel Sefström discovered a new element, which he named vanadium. It was later revealed that this was identical to the metal discovered earlier by Andrés Manuel del Río. Del Río's "brown lead" was also rediscovered, in 1838 in Zimapan, Hidalgo, Mexico, and was named vanadinite because of its high vanadium content. Other ...

Vanadium is a trace metal that is relatively abundant in the Earth (~100 part per million in the upper crust). [1] Vanadium is mobilized from minerals through weathering and transported to the ocean. Vanadium can enter the atmosphere through wind erosion and volcanic emissions [1] and will remain there until it is removed by precipitation. [1]
In 1845, Rose published the discovery of a new element pelopium, which he had found in the mineral tantalite. [11] After subsequent research, pelopium was identified to be a mixture of tantalum and niobium. [12] In 1830, Heinrich Rose was elected a foreign member of the Royal Swedish Academy of Sciences.
