ProcessingVanadium from Sediments – Different to Magnetites

”Thevanadium hosted in sediments and sandstones typical of the US arecommonly mined firstly for uranium then vanadium as a co-product. Theprocessing of these ores requires solvent extraction to separate thevanadium and uranium fractions which is then followed by an ionexchange stage which leaves the vanadium in the acid solution. Theacidic solution is oxidised to allow the recovery of vanadium fromthe organic salts by means of soda ash. The resultant slag producedthen undergoes a similar pyrometallurgical process to recover FeV andV2O5 for different uses.”

”Emergingplayers in the vanadium sector that are investigating sedimentaryhosted deposits of vanadium (different to uranium-vanadiumsedimentary deposits) include: Energizer Resources (TSX:EGX) with itsGreen Giant deposit in Madagascar; Sino Vanadium (TSX:SGX) with itsDaquan project in China; and American Vanadium (TSX:AVC) which ownsthe Gibilleni deposit in Nevada, USA.”

P.S.Energizer Resources (TSX:EGX) is now NextSourceMaterials Inc (TSX:NEXT)

Vanadium

”Daejonis a unique sediment hosted shale/slate bed vanadium project whichhas the potential to produce high purity vanadium pentoxide (V2O5).Approximately 5% of vanadium mineral occurrences are sediment hostedand 95% are magnetite hosted (as discovered in Western Australia,South Africa etc.) ”
