How did the Mina Ragra deposit in Peru contribute to early vanadium production?

The Mina Ragra deposit in Peru played a pivotal role in the early commercialization of vanadium. In 1905, Antenor Riza Patron discovered this large asphaltite deposit, which contained rich concentrations of the vanadium-bearing mineral patronite.12

Following this discovery, the American Vanadium Company utilized the site to produce ferrovanadium on a commercial scale for the first time in 1907. This development was significant because it helped establish vanadium as a viable and important alloying element for steel and iron, marking a major milestone in the history of vanadium processing. While the deposit was once a primary source, it has since been materially depleted.12
