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. [1] Vanadium was first discovered by the Spanish-Mexican mineralogist Andrés Manuel del Río in 1801. He named it erythronium.
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.
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.
Donnel Foster Hewett (June 24, 1881, Irwin, Pennsylvania – February 5, 1971) was an American geologist and mineralogist, known for his leading role in the 1905 discovery of the Minas Ragra vanadium ore deposit in Peru. [1] This ore deposit was the world's principal source of vanadium for more than 30 years.
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 ...
Berzelius discovered cerium in 1803 [29] and selenium in 1817. [30] Berzelius also discovered how to isolate silicon in 1824, [ 31 ] and thorium in 1824. [ 32 ] [ 33 ] Students working in Berzelius's laboratory also discovered lithium , lanthanum , and vanadium .

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]
