Salt Roast - A summary The Bushveld Perspective

2019-9-1  More typically that Vanadium Slag (at anywhere between 20%- 33% Vanadium) is put through a salt roast process as we are about to discuss instead. It’s worth pointing out that Vanadium made through this classic “secondary” production process has a recovery of about 55-60%, so very wasteful compared with our Primary production method.
