In this paper, potassium salt roasting additives were applied to extract vanadium from vanadium–titanium magnetite concentrate. Meanwhile, the mechanisms of potassium salt roasting and acid leaching kinetics were investigated. The results indicate that potassium salt roasting additives are more efficient than sodium and calcium salt …

The vanadium extraction of this ore into metal did not exceed 10 % during smelting of metallized pellets in an arc steelmaking furnace, but special techniques could raise this to 85 %.

Vanadium is an important strategic resource which is mainly used in steel industry, redox flow batteries, medical field, and catalysts. In addition to vanadium titanomagnetic in China, stone coal is the most important vanadium-containing resource which accounts for more than 87% of the domestic reserve of vanadium [1,2,3,4].Thus, …
