Traditional nuclear science models nuclear forces as purely conservative forces, but this assumption may only be accurate at high energies. If non-conservative forces are at play in smelting facility then there would be little if any conversion of mass into energy. I guess that would mean the iron at the facility would be slightly more massive than iron born from stellar fusion. Harry
