Does gold “burn”? Not in the common sense, but it can both melt and vaporise (at about 1000 C and 3000 C respectively). It can also form stable oxides, and is probably more likely to do so when condensing from a liquid or vapour state mixed with air. So the answer is twofold: A lot of the gold would melt vaporise before precipitating as very fine particles that are spread with the wind, while an amount of it would likely form oxides in the process. The result would be a bunch of gold and gold oxide dust spread over a vast area, probably taking years before all of it reaches the ground.
