1. Introduction Vanadium is obtained from several distinctly different minerals and ores [ 1- 3 ]. However, a common step in the early stages of chemical processing is to roast vanadium, in the form of a compound oxide, with a sodium salt in an oxidizing atmosphere. Sodium vanadate is selectively leached from the product with hot water [ 4-6 ].
