1. Introduction. Vanadium is an important strategic metal and is widely used in the iron and steel industry, as well as in non-ferrous alloys due to its excellent hardness, tensile strength, and corrosion resistance [1].Vanadium accounts for only 0.02% of the crustal weight, which although is a higher abundance than that of copper, zinc, and …

Titaniferous magnetite hard rock deposits are common throughout the world. Previously they have been processed to recover vanadium using the standard salt roast process, however the economics based on vanadium alone can be marginal due to the high CAPEX and OPEX, making it vulnerable in a volatile vanadium market.
