Vanadium extraction from titano-magnetite by using hydrofluoric acid was put forward. The process of low intensity magnetic separation, hydrofluoric acid …
The mineral coulsonite (FeV 2 O 4) is often associated with magnetite (Radtke, 1962) and forms a series with magnetite and chromite, FeCr 2 O 4 (Reznitsky …
Abstract: In this paper, potassium salt roasting additives were applied to extract vanadium from vanadium–titanium magnetite concentrate. Meanwhile, the mechanisms of …
titions between magnetite and ilmenite in titanomagnetites (Schuiling and Feenstra, 1980). Vanadium in weathered mineral deposits is known to occur in clay, with …
Many technologies exist for the treatment of titaniferous magnetites that contain vanadium. Each process is designed based on the relative amounts of titanium, …

The main methods of extracting vanadium from vanadium-titanium magnetite are direct extraction and indirect extraction.
In this study, a new vanadium extraction process from vanadium titano-magnetite (VTM) featuring calcification roasting and (NH 4) 2 C 2 O 4 solution leaching …
The vanadium mineral coulsonite, FeV 2 O 4 forms series with chromite, FeCr 2 O 4 and magnetite, Fe 3 O 4. Most of the vanadium is produced from titanomagnetites either directly from titanomagnetite ores/concentrates or indirectly from …
Titaniferous magnetite deposits are a significant source of vanadium for use in high strength steel alloying and other chemical applications._x000D_. The mineralogy of the …
