Vanadium is the fifth most abundant transition metal in the earth's crust, often found with titanium and iron in their ores, and significant concentrations are found in certain coal and oil deposits, such as crude and shale oils.
The discovery of vanadium happened twice. The discovery of vanadium was claimed first by Andres Manuel del Rio (a Spanish mineralogist) at Mexico City in 1803. He prepared a number of salts from a material contained in brown lead (now called vanadite, from a mine near Hidalgo in Northern Mexico).
