Abstract: An innovative method for recovering valuable elements from vanadium-bearing titanomagnetite is proposed. This method in-volves two procedures: low-temperature roasting of vanadium-bearing titanomagnetite and water leaching of roasting slag. During the roast-ing process, the reduction of iron oxides to metallic iron, the sodium ...Web

The common vanadium ores are vanadinite, patronite (vanadium sulfide, VS 4), and carnotite (potassium uranyl vanadate, K 2 (UO 2) 2 (VO 4) 2). Vanadium is also abundant in Venezuelan oil, to the extent that its ash is a commercial source of vanadium pentoxide (V 2 O 5). It has been suggested that plants living at the time these oil deposits ...Web

The relationship between iron and vanadium in the body system is complex and not fully understood. However, the following have been reported: similar to iron, transferrin binds about 90% of the vanadium in plasma, but it is not yet established if its release is mediated through ferritin [31]. Studies have, however, indicated that the iron …Web
