Hi Shellbell,
It is completely different from Mr Frey's version, (well the 5 new steps are)
Michaels Patent also talks about its use in black mass ( recycled anode) to achieve the 99% TGC..
It's pretty poor that we as shareholders don't know if we are using the one purification method for black mass and spherical graphite, or if we need to use two different purification methods.
@Names little I agree with your comments, The only positive I see with the patent, we have moved away from the Australian approval process, we wouldn't want another time delay with RNU objecting holding up any advancements on recycling black mass/anode scrap.
(20min delay)
