That's funny Bobby, your clone Derek Nilsen just posted a week or so
ago, and I told him how to properly clean the salvaged aluminum,
identical as you just posted.... hmmmm.
Need a reminder? Here you go:

There are looking to be some odd coincidences between you and Derek.
Derek owns the "make chemicals" site (but didn't even know why
aluminum powder is sometimes coated). You post under a few newsgroups
telling people about this site as well... and then state exactly the
same process I told Derek a week ago... seems a bit odd
But never-the-less, the salvaged aluminum is still junk compared to
most all types of flake aluminum, due to the fact that the salvaged is
atomized aluminum, and on top of that, coated in a wax.
Thanks,
Bob
