Vanadium. Its role for humans

Vanadium is the 21st most abundant element in the Earth's crust and the 2nd-to-most abundant transition metal in sea water. The element is ubiquitous also in freshwater and nutrients. The average body load of a human individual amounts to 1 mg. The omnipresence of vanadium hampers checks directed to

Influence of processing factors on the sheared-edge

2020-2-2  The vanadium bearing DP steel conditions possess higher strength at the same hole expansion levels or higher hole expansion ratios at the same strength levels compared with vanadium free steel conditions, which is probably due to the strengthening of the ferrite phase from the vanadium. This strengthening was shown by the nano-hardness data. (4)

A Review on Types of Vanadium Deposits and Process

Because vanadium mainly exists as a trace element in minerals, vanadium deposit refers to a deposit capable of recovering vanadium from by-products rather than a reserve where vanadium-enriched minerals are locally concentrated. Vanadium deposits are largely divided into four types: VTM, SSV, shale-hosted vanadium, and vanadate deposits.

Microbial Community Responses to Vanadium

2019-3-5  Vanadium widely exists in the Earth's crust alongside minerals, crude oil, and coal (Huang et al., 2015). Global and European vanadium concentrations in soil typically range between 90 and 60 mg/kg (Yang, Tang, et al., 2014). In China, the soil background levels of vanadium are estimated at 82 mg/kg (Teng et al., 2011).
