Vanadium processing17 Mar 2021 07:41
for those who may suddenly be interested in the minutae of Vanadium processing, specifically in relation to the claims that a new entrant to the market will suddenly be able to produce Vanadium at a lower price than any of the existing primary miners here are some facts:
1) None of the world's main primary Vanadium producers (Largo, Rhovan, Bushveld Vametco and Vanchem) use black shale as a source of their ore - they all use Vanadium-Titano Magnetite (VTM) ores.
2) VTM ores allow the processed rock to be concentrate to >1.5% Vanadium content because the V2O5 is hosted in the magnetic fraction, so magnetic concentration is a possibility. It is not a possibility in black shales resources so no such concentration is possible and all the rock has to be sent through the entire process. I note that some have stated that VTM ores 'require' magnetic concentration, as if this is a bad thing, it is not, it allows you to start with an even better material and not process millions of tonnes of unnecessary ore.
3) There are dozens of black shale (also known as stone coal) resources in China - Terry Perles described these at the 4th Vanitec energy storage meeting ( https://www.thebushveldperspective.com/blog/public-articles-1/post/vanitec-4th-energy-storage-meeting-part-1-274 )
"Similar were stone coal deposits, TP mentioned that he knew of dozens of Vanadium bearing stone coal deposits in China but as ever the ore grade was important, and as magnetic concentration could not be used, unlike VTM ores, stone coal was always going to be in a difficult position when compared with VTM ores. TP mentioned that Chinese stone coal Vanadium producers had told him that they needed virgin grades of 0.8% or better to be economically extractable."
4) in other Vanitec presentations Terry Perles has noted that these chinese stone coal processes do not get turned on until the price of Vanadium is high, typically over $50/kgV (FeV)
Draw your own conclusions as to whether a new entrant with a process that is not used at major scales can reasonably expect to be 'lowest cost producer' - we've seen this all before - King River Copper, Aura Energy's Haggan, etc project all claim to have 'massive' resources and yet they can never get their mines built. What does this tell you ?
