The gold will again take on the appearance of metal. If you've followed the procedure carefully and used filters, the gold should be 99.95% pure with negligible losses. Platinum. If you had platinum in your gold, it will not dissolve, to any appreciable degree, in the room temperature aqua regia.
Gold fingers are typically found on PCI cards, ISA cards, or on Memory sims/dimms/etc. They create the corrosion free connection between the computer and the expansion card. This process can also be used to recover gold from CPU such as Pentium Pro, or Cyrix or older 486 and lower generation chips.
Dietary nitrate may also come from drinking water. Though the U.S. Environmental Protection Agency has set a maximum limit for nitrate in drinking water, the levels of nitrate in water vary greatly and may be quite high in some locations. Nitrate content in both drinking water and vegetables is influenced by the use of nitrate fertilizers.
