My CRC handbook lists KCN, potassium cyanide as also dissolving gold. That is a new one on me. But to say that is all that gold will dissolve in is not quite accurate, this is only accurate at certain temperatures. Gold, copper and silver dissolve in each other once the temperature is high enough for one of them to melt. That is how alloys of these metals are formed. Almost always the alloy has a melting point lower than any of the components. But in terms of aquous solutions that gold dissolves in, then it is pretty well just aqua regia and KCN.
I am still trying to figure this amalgam thing out.
