In 1830, N. SefstrÃ¶m discovered vanadium in some iron ores. Vanadium is a white metal that possesses good resistance to corrosion by alkalis, and sulphuric and hydrochloric acid. Vanadium occurs in approximately sixty-five different minerals and in carbon deposits such as crude oil, coal, oil shale and tar sands, but is never found unbound in nature.
