what do you want to point out? Separating gasses from each other are standard industrial processes, that's not rocket science. Similar technologies are used with SMR technologies producing H2.

removing specific metal inclusions from graphitic carbon while preserving the characteristics of the graphitic carbon, is probably not your average industrial process, hence the research that HZR puts into this. But even this is down to getting the last few percentage points out, before it can really be used and applied with higher value products like LIB anodes.

questioning purity / conversion levels and probable weaknesses of the HZR process is ok, but try to put it into perspective: "even more work" sounds like a scream of frustration, but actually necessary process steps are very well defined, and on the gas side no issue from my perspective.
