The Minas Ragra was a large vanadium mine in the Pasco Region of Peru. The deposit was discovered by a United States Geological Survey expedition on November 20. 1905.[1] Members of this expeditions were Donnel Foster Hewett and José J. Bravo In this deposit the mineral patrónite was first discovered by a member of the expedition Antenor Rizo-Patron.[2] A mine was established in very short time by the Vanadium Corporation of America. By 1914 75% of the world vanadium ore production was coming from the Minas Ragra in Peru, making the mine to the world leading producer of vanadium.[3] With the production of vanadium as side product of uranium mining from carnotite the mine had to close in 1955.
