Would a high iron content world have particular effects on its more common minerals/elements?
Depends on history of formation.
In the proto-planetary disk, everything is kinda uniform. But once they go above certain size there is a lot of energy added via collisions, combine that with heating ...

I've not read very thoroughly on this, but my interpretation of planetary formation implies that if such elements are abundant during the formation of planets a metal rich planet would have a variety ...

If you're building a mega-structure like a Banks Orbital, then your civilization has mastered spaceflight to the point that it's a non-event. Your people can hop out to the Kuiper Belt the ...

Seal the Ingots in the Gold
As the various metal ingots are made take them into a nitrogen gas chamber and seal them in gold foil. The gold does not react and acts as a barrier against the air thus ...

I believe ingots would be sufficient. Over the timescale of centuries or single digit millennia, ingots will be resistant to oxidation anyway. Certainly those at the surface of these large stacks will ...

Passivating layers will help. Avoid water and especially chlorides. Ignore oxidation when choosing ingot size.
A combination of a thick passivating layer and a dry atmosphere should slow corrosion to ...

Airless Chambers
The atmosphere is artificially generated. Some pockets of the structure have no atmosphere. Or perhaps they have a different oxygen-free atmosphere. For example pure nitrogen like ...

Two keywords here: pigs and cosmoline.
First, pigs are large ingots, typically close to the size of the smelter crucible that originally produced the pure metal. This (as suggesed by L.Dutch) ...

If you want to store it for very long time, first of all you want to minimize the available surface: it both reduces oxidation and depredation.
While a stash of 1 billion ingots 1 kg each can be taken ...
