Lanthanum (La)
Second most abundant element at the Guayana Highlands complex with 360,000 tonnes of probable reserves. Essential for high-end optics, nickel-metal hydride batteries, and refinery catalysts.
High demand stems from precision optics (superior refractive indices for camera lenses, telescopes, and military optics) and NiMH batteries powering hybrid vehicles. Optical-grade lanthanum commands significant premiums in the precision lens market.
Reserve Valuation
At current oxide prices (~$2/kg for La₂O₃), the 360,000 tonnes of probable lanthanum reserves at the Guayana Highlands complex represent an estimated in-ground value of $720 million USD. Optical-grade lanthanum commands significant premiums in the precision lens market.
Strategic Relevance
Lanthanum gives its name to the entire lanthanide group. Its high demand stems from two critical sectors: precision optics (where lanthanum glass provides superior refractive indices for camera lenses, telescopes, and military optics) and NiMH batteries that power hybrid vehicles and backup energy systems. The Guayana Highlands complex holds 360,000 tonnes of this strategic element as probable reserves.
