processing of vanadium ore
Vanadium Mining - Encyclopedia of Arkansas
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.

An interesting description is presented of mining and processing low-grade vanadium ore in the Andes Mountains in Peru, South America, at a height of 14, 000 feet. The ore contains large proportions of silicates and aluminium salts with only 1 per cent. of vanadium. The vanadium content of the ore after processing ready for bagging ranged from 0.54 per cent. to 3.62 per cent.
