Two differing methods for vanadium extraction : chemistry

Vanadates progressively dehydrate as the solution is acidified, eventually giving a precipitate of hydrated vanadium(V) oxide. In strongly acidic solutions though, vanadium(V) oxide redissolves to give dioxovanadium(V), a consequence of the amphotericity of vanadium(V) oxide.

Uranium Mining and Extraction from Ore – Stanford University

The chemistry of these processes is very similar to the extraction methods, except that the leaching solution is pumped into the uranium ore while it is still in the ground. [2,5] Fig. 3 shows a schematic of the in-situ leaching process, in which the leaching solution is pumped into the ore zone containing the uranium ore. The leaching solution is pumped back up into a plant for further ...

Vanadium - Wikipedia

Vanadium is a chemical element with symbol V and atomic number 23. It is a hard, silvery-grey, ductile, and malleable transition metal. The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) somewhat stabilizes the free metal against further oxidation.

Vanadium - The Royal Society of Chemistry

Silver vanadium oxides have a role in battery chemistry. The first large scale industrial use of vanadium metal was a century ago in the steels used to fashion the chassis of the Ford Model T car, and steel remains the main use of vanadium metal. Because vanadium is a light transition metal, not a "heavy metal" as often incorrectly claimed in the toxicology literature, vanadium metal ...
