Vanadium
from ATI Wah Chang

Vanadium is widely dispersed in the earth's crust occurring in many types of deposits. Most vanadium is currently obtained as a by-product or co-product from titanomagnetites, petroleum, uranium ores, and phosphate rock. Table 1 shows the abundance of vanadium in the earth's crust relative to some... [See More]
