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.
Most vanadium is used as a steel alloy called ferrovanadium. Ferrovanadium is produced directly by reducing a mixture of vanadium oxide, iron oxides and iron in an electric furnace. The vanadium ends up in pig iron produced from vanadium-bearing magnetite. Depending on the ore used, the slag contains up to 25% of vanadium.
