Superb ! Love the way you just do these things as if you're just changing a tyre ;) The rate of Cl2 gas bubbles looks really high - it might go faster in a column rather than a beaker, with a slower gas rate, with the gas hitting more of the metal as it rises. With a column, you could also duct away the waste chlorine gas into a jar of caustic soda solution to neutralize the waste gas. Chances are that a UV light would also help in there. The UV would help the Chlorine gas to split and whack the gold quicker.

Nicely done. Atomization of alloyed gold and chlorination of hydrochloric acid is desirable because the gaseous emissions are easily scrubbed and abated. You chlorinated with gas and it's also possible to use perchlorate directly in the reactor instead but clearly the use of gaseous chlorine as the oxidizer is cleaner, resulting in a quick dissolution and fewer contaminants.

Such elegant, pure method of gold dissolving! But definitely, you waste a lot of chemicals and chlorine, the rate of gas production for such reactions should be such, that bubbles coming from tube dissolve and disappear before floating to the top of the solution. I remember someone in the past who wrote a comment about using a big flask filled only to 1/4-1/3 for this, bubbling to the moment all air is displaced from the flask by chlorine, and then stop generation and stirring to the moment chlorine is used up. An alternative could be a tall and narrow vessel, so gas needs to bubble through more mixture and gets more absorption and reaction time. I hoped only that at the end you will precipitate gold with SO2, making it full gas workup XD

An aquarium CO2 diffuser might be the easiest way to make smaller bubbles and dissolve more of the chlorine gas into solution. Agitating the gold will speed up the process but not change the yield or chlorine consumption. Using a more robust magnetic stirrer or a mechanical shaft stirrer would be my choice for keeping fresh solution in contact with the metal. It does not really matter if it only dissolves gold on the surface only except for some small saving in time.
