In 1966, Union Carbide began mining operations and stockpiling vanadium ore in Garland County. Construction of the vanadium processing mill was completed in 1967, and vanadium oxide was produced for the first time in Arkansas in 1968. By 1970, Arkansas was a major vanadium-producing state in the nation.
