GEOLOGY AND RESOURCES OF VANADIUM DEPOSITS GEOLOGY AND RESOURCES OF BASEMETAL VANADATE DEPOSITS By R P FISCHER ABSTRACT Almost all basemetal vanadate deposits occur in the oxidized zones of basemetal vein and replacement deposits They consist of basemetal vanadate minerals and wulfenite the molybdate of lead These minerals

The extraction and recovery process of vanadium as a byproduct from the tailings of a uranium processing plant poses many problems In this study vanadium is recovered from impounded resininpulp 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

Vanadium was discovered in 1801 by the Spanish scientist Andres Manuel del Rio Del Rio discovered the new element in brown lead ore now known to be the mineral vanadinite Pb 5 VO 4 3 Cl in New Spain Mexico Del Rio had moved to Mexico as a professor of Chemistry and Mineralogy at the Royal School of Mines Mexico City

Vanadium naturally occurs in about 65 different minerals including vanadinite the ore of lead and vanadium from which Del Rio first isolated it In the US it is most commonly found in sandstones which are rich in uranium ores Vanadium is also found carbonrich deposits such as coal oil shale crude oil and tar sands While minor amounts
