Vanadium Extraction Process

The extraction and recovery process of vanadium as a by-product from the tailings of a uranium processing plant poses many problems. In this study vanadium is recovered from impounded resin-in-pulp tailings and from the current tailings of a uranium plant which did not include a circuit for vanadium recovery in its initial design. Since the vanadium content is quite low, capital expenditures ...

Estimation of vanadium in plant materials. 2. Use of the ...

2. The red colour developed by vanadates with H2O2 can be used, by measurement with a photo-electric colorimeter, to estimate as little as 3 µg of V, but, owing to the presence of Ti in plant material, it is necessary to add NaF to inhibit the colour developed by Ti salts, and hence the lower level of estimation is raised to 5 µg. of V. It is most satisfactory to work at wavelengths of 450 ...

Vanadium - Wikipedia

Vanadium is a chemical element with the symbol V and atomic number 23. It is a hard, silvery-grey, 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.. Andrés Manuel del Río discovered compounds of vanadium in 1801 in Mexico by ...
