rare earth re-cycling starting to get momentum, page-5

'It's not that simple because the raw rare earth itself still needs to be converted into specific specs'

Can anyone explain how these specific specs are formulated?

We are dealing with base elements on the periodic table.

They can be mixed for sure, but apart from mixing how else are they specific. Is someone processing the elements into different elements or something esoteric.

I understand how Strontium 89 can produce Strontium 90 and then Yttrium 90 can be milked. LYC are not in the business of radioactive generators or reactors so we can dismiss this sort of added value.

But what are LYC doing to the base elements that changes them in any way apart from mixing them for a customer?

Do we have an chemical engineers that can shed any light?
