I dropped the acid in to quick, 250ml in about half an hour. After resetting I pulled the acid drip way back and the same amount of acid lasted greater than 3 hours of continuous chlorine gas flow. It’s was my inexperience with using chlorine to dissolve gold.

Beautiful bar! Really enjoying all the different methods you have been demonstrating lately. Fascinating stuff.

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.

Are you loosing much Cl2 out the top of the reaction beaker? Might be worth giving the bubbles more time/surface area to dissolve.

I can't help but feeling that a lot of the chlorine gas went up out of the fume hood without reacting with any gold at all (although it may have corroded the fan). If you were doing this on a large scale then it would probably be worthwhile to capture the gas and cycle it back into the process.

What is the mechanism involved here compared to aqua regia? Merely increasing the concentration of Cl- ions such that they attack the gold? Also RE: efficiency, I suspect something like the chamber process could be used. Put just enough distilled water in with the gold (no HCl), then fill the chamber with an excess of Cl2, seal it and wait.

LOVE your videos man keep it up! where can I find your eBay?

the fact that only a gas has been added to dissolve gold would probably lower even further any risks of contamination, it's a great idea! I wonder though if it would be possible to cycle the chlorine produced back again into the beaker, because i expect alot of chlorine is being is lost in the air

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.

I watch all your videos and i always have a question in my head. it might be a stupid question but it drives me crazy. You ended up here with 48grams of gold at the end. how much however does the gold powder weigh if its dried and before its melted? Also and this one really gets me. when you have the gold solution dissolved completely sat in approx. 500ml of solution lets say. Does that 500ml of liquid in that container weigh 48grams more than an identical container just with 500ml of liquid and with no gold dissolved solution ? like i say might be really stupid but it drives me crazy thinking about it

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.

Condensation will usually be from water vapour so close to distilled. Water would not be an issue but if there is some splashing it could be the metal solution and contain some values. The amounts of loss would be small but it is simple enough to wash them into the place you want rather than down the drain when you wash the glassware. If it is a strong acid then it is better to rinse the drops into the beaker rather than have them eat holes slowly into your counter top where they may drop.

Electrolysis of salt solution will produce first bleach, and then sodium perchlorate, which could be used to produce chlorine gas. Or you could just use the perchlorate or even the bleach to dissolve the gold. If the point is to refine gold with household chemicals just use bleach or hydrogen peroxide. As long as you have the HCl to solublize the gold ions, any descent oxidizer will do.
