Fanadium - no Vanchem is owned by Duferco. Evraz Highveld simply sold them Vanadium sla-g to enrich the ore that they were getting from Mapochs. Duferco then probably sold Ferrovanadium back to highveld. When Evraz pulled out of SA Highveld shut and both Mapochs and Vanchem went into business rescue.
At around the same time and on the other side of Johannesburg Evraz sold the Vametco mine and processing plant to BMN. SA said goodbye to Evraz, and hello to Bushveld.
Fanadium - we bought Vametco from Evraz 18 months ago. Vanchem is our second processing plant - this has been in business rescue since Evraz pulled out of SA and the Highveld Steel plant was closed down.
Richken - sorry another correction - the 1.5%-2.5% grades are the in-concentrate concentrations. The total rock concentrations are around 0.7%. So a little more trucking and crushing to do but simple magnetic separation gives you starting material with around 2% V2O5 concentrations - that is what gets fed to the rotary kiln.
As Ophidian says it is not the amount of V2O5 that we've got in the ground that matters. It's the amount that we can process with our processing plants (1 kiln going up to 4 kilns soon). Even processing at 10,000 tonnes per year what we have would last for 100 years.
RE: Lithium batteries not suitable for utility scale08 Aug 2019 19:43
It seems that Commissioner Kennedy is not just concerned about the risks of thermal runaway of Lithium-ion batteries but also the generation of Hydrogen Fluoride gas. This of course combines with moisture in the lungs to produce Hydrofluoric acid, one of, if not the most, dangerous acids known to science.
I wonder how long it will be before the class action suits start.
