Re: Size of the pile:
In the first original post I wonder if they meant to say "aluminum" rather than "alumina".
"Alumina" is aluminum oxide -most people know it as the abrasive in common brown-colored sand paper.
Seems to me a story about missing metal pledged as collateral would be talking about billets of metallic aluminum, not about piles of alumina sand (or fine ceramic powder).
