Bushveld Vametco Alloys (Pty) Ltd. operates an open-pit mine supplying ore to a vanadium processing plant located on the same properties.
The operation owns the new order mining right for vanadium and other associated minerals over a portion of the remaining extent of Portion 1 of the farm Uitvalgrond 431 JQ, and Portion 1 of the farm Krokodilkraal 426 JQ.
The Vametco mine is an opencast mine along a strike of approximately 3,5 km, extending in a west-east direction.
The ore body is well-defined, continuous, and dips in a north-east direction at approximately 19° - 20°.
The mine is based on a JORC-compliant resource of 181,5 Mt, including 46,2 Mt reserves.
In-magnetite vanadium grades average approximately 2% V2O5, with a life of mine of more than 30 years.
Vametco’s processing plant receives ore from the co-located Vametco mine.
Vametco utilises the standard salt-roast and leach process to produce a steel-alloying vanadium carbon nitride product, called Bushveld nitro-vanadium.
Vametco employs the standard salt-roast and leach process to produce Bushveld nitro-vanadium.
Crushing, milling and magnetic separation to produce a magnetite concentrate with average grades of 2% V2O5 in-magnetite
Sodium salt roasting the concentrate in a kiln at ±1 150°C to form a water-soluble sodium vanadates material
Leaching and purification, with dissolution of roasted vanadium concentrate in water, purification and precipitation of vanadium through the addition of ammonium sulphate, followed by drying and then processing in a reducing environment to produce a Modified Vanadium Oxide (MVO) product
Briquetting and feeding the MVO into a shaft induction furnace in a nitrogen atmosphere to produce nitro-vanadium, which is used as a micro-alloy in steel production
