RE:RE:On 2nd thought Rapid, maybe a little higher, here is whyIf less than 1% of rare earths in starting concentrate consisted of (releatively rare) holmium through lutetium, then separation of lanthanum through dysprosium from holmium through lutetium was already 99%pure before Ucore did anything.
Similarly, regarding Ryan's claim of 98.5% pure Dy mixed with Tb,, he ddn't say what the starting point for this separation was - wouldn't put it past Ryan to be misleading. And for all we know, maybe Ucore ran the same sample through many cycles, at huge cost, to obtain a very small quantity of that claimed purity.
