Mustpow's input detailing how complex it is to firstly to beneficiate to produce a suitable concentrate then the limitations with known processes as to what can be produced at the expense of something else.... Rather than less, being doubtful, I'm more convinced than ever TNG/SMS have 'scienced the sh!t out of this' and created a truly game changing refining process with TIVAN.
Its been bugging me for sometime as to why other V-Ti-iron ore explorers haven't jumped on board spruiking a tie up with TNG & I thought that higher grades may not work as well through the TIVAN process.
Now seeing that beneficiation will get them mostly to the same concentrations in feedstock to the refinery, I'm more of the opinion PB is sticking with the tier one approach. IOW TIVAN is the bomb, & TNG are dealing with the companies/organisations they know have the financial strength to realistically bring the first, second, third TIVAN plants to life.
Possibly Reading way too much into this, I know, but that's my current opinion of this. That TIVAN is a disruptive process & those in the know, would realise this.
