Another method for vanadium extraction is the sub-molten salt process studied by Wang et al. (2014). This is related to the hydroxide roasting process discussed above, and relies on the reduced melting point of partially hydrated sodium hydroxide. Vanadium slag is combined with 80% NaOH which melts at around 150 °C (Pickering, 1893).

Does vanadium form concentrated deposits?

Unlike other metals such as copper, nickel or zinc, vanadium does not form concentrated deposits. Owing to the similarities between the V 3+ and Fe 3+ cations, vanadium is often found as a minor component of iron minerals. The vanadium mineral coulsonite, FeV 2 O 4 forms series with chromite, FeCr2 O 4 and magnetite, Fe 3 O 4.
