The aluminum metals
Gold and platinum will no react with HNO3 due to their low reactivity. Aluminum also will not react with HNO3 despite its relatively high reactivity because it has a protective layer of aluminum oxide on it.
of course since the item is metal (precious) it will show on your metal detector unless of course you've blocked gold or nickel .
Yes, aluminum is more reactive than gold. Aluminum is more prone to oxidation and reacts readily with oxygen in the air, whereas gold is a noble metal and does not easily react with other elements.
the gold metal
no there was no electricity i think

Aluminum
Gold is a very unreactive element, so it occurs as gold metal in nature. However, aluminum is more reactive, and so it occurs in aluminum ore (aluminum oxide) in nature, not as aluminum metal.
It depends on the metal. Gold will react with other elements with great difficulty. There are gold compounds, but if you have a solid chunk of gold it'll basically sit there and do nothing. Titanium and aluminum are pretty reactive. Iron reacts pretty well with oxygen. At the far end of the scale, sodium goes out of its way to react with other elements.

Gold is a metal that does not react with dilute hydrochloric acid.
