It depends, in ionic state gold is a salt of gold ions and chloride ions, much like sodium metal ions and chlorides ions make table salt NaCl. the gold salt in solution can be evaporated to a dry salt of gold chloride, as long as the temperature is kept lower than the vocalization point of the gold salt.
Evaporation can happen at lower temperatures there is no need to boil the solution, during boiling the fumes and gases can carry liquids as the bubbles of gases burst at the surface of the boiling liquid, this can splash or spit gold out with the fine mist, here our loss of gold is not from volatility of the solution, but from mechanical spitting of the liquid.
Keeping the solution temperature lower than boiling, and a watch glass to re-flux salts and gold stays in the pot.
The salts can be evaporated from solution, if the temperature is too high during drying of the salts we can volatilize the gold as smoke.
if we can slowly dry the gold without raising the heat we could drive the chloride off as gas and reduce the gold.
But this would not be easy to do without some loss of gold.
Here is where we do not want to incinerate a material with gold salts, if we must (like a solution or gold solution of purple of Cassius), a having a carbon source (like old filters) and using some sodium hydroxide may help to convert some of the gold, drive off chlorides, in an attempt to reduce the gold and rid it of chloride through evaporation, before the incineration process to keep from losing gold as much as possible, normally this is done with dirty solutions oe solutions with much base metals besides tin, like copper, the copper prefers to be a chloride over gold, here this can also be somewhat helpful, as the copper chloride can be heated to drive off chlorides, and not lose the reduced gold, as long as the temperature is kept low enough...
So it depends, gold in ionic state can go up in smoke, or we can reduce it to metal with control of the temperature and environment...
