The extraction of vanadium from titanomagnetites and other sources
The vanadium mineral coulsonite, FeV 2 O 4 forms series with chromite, FeCr2 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 the slag left from smelting titanomagnetite ores. Titanomagnetite ores are associated with …

Pre-concentration of vanadium from stone coal by gravity separation
According to the research of Ni et al. (2010), when vanadium grade is 0.7%, the production cost of 1 t V 2 O 5 from stone coal is 86,295 CNY. If the V 2 O 5 grade of raw material improved from 0.7% to 0.8%, the production cost of 1 t V 2 O 5 would decrease by about 4000 CNY and the profit increase by 29%. Further, over 60% of the stone coal ...

Vanadium mineralization occurs in oxide-rich horizons within layered metagabbro zones of the Sinarsuk deposit, West Greenland. The main oxide minerals are vanadiferous magnetite and ilmenite, comprising 30% to 90% of the rock volume and the ratio of magnetite to ilmenite ranges from 3:2 to 4:1. Ore microscopy shows that magnetite and ilmenite vary …

Vanadium
A silvery metal that resists corrosion. About 80% of the vanadium produced is used as a steel additive. Vanadium-steel alloys are very tough and are used for armour plate, axles, tools, piston rods and crankshafts. Less than 1% of vanadium, and as little chromium, makes steel shock resistant and vibration resistant.
