Ah I did actually read that post and wasn’t sure if these changes had been influenced by it. I think it’s a good idea overall, but like you said the original tantalite into the crucible step should be preserved, since otherwise the process is quite a lot harde. It sort of has you jump up to MV and extreme amounts of manual labor for aluminium, and (in my opinion) a dispraportionate amount of steam setup just to run the electrolyzer briefly for this material you really only need a small handful of for a long while
